What brand of oil should I use

[Texas Diesel]

Wayne, I never, ever, even thought or indicated that you would doctor the pictures! I sure hope I didnt give that impression.

By biased I meant, well lets not go back there, you know what I meant and have adequately responded.

Ok I have a question, why would you spend more money to run a pure synthetic that costs more, other than below 0* weather, when delo has been proven for many years to do just as well (if not better)??



My valve covers are just as clean as the pics with 181K miles on the truck, so are the 92's with 380K. I change the oil every 3k as I always have, it only takes me 20 minutes or less so I don't care about extended oil drains.



I'm not saying AMS is not a great oil, I'm sure it is, but why should I chose it over Delo?? If there is a big plus to running it, I would but I've never seen any data that would convert me.



are there any 700K+ mile motors out there running AMS??

 

[Sled Puller]

zjones, I can only speak for myself.



I drive 120 miles or more each day to work. I wanted to extend drains farther than I was on petro.

I always went 5000 to 6000 on Shell Rotella, before that Wolf's Head. (Pennzoil)

I did that on all my engines, gas and diesel.

Never had an oil related failure.



Amsoil was and still is, to my knowledge, the only oil company that advocates and preachs extended drains, and backs it up with a 30 year flawless record.



Easier starts are nice, even in the 40s you can tell the difference.



It keeps things a little cooler, and doesn't burn up in extreme heat. Burying an 1800 degree pyro does make me a touch nervous.

Is there a Dodge Cummins with big mileage on Amsoil? I'm sure there is, but I don't know how to find it.



The technical properties for Amsoil are better than any pretroleum oil mentioned on this board, as they should be.



Is the price worth the extra performance?



Only you can decide that for your situation.





But why change, if you are happy with the performance of what you are running.

just switched to Schaeffer's...

I recently switched from Valvoline Premium Blue 2000 15w40 to Schaeffer's Supreme 7000 15w40 (synthetic blend).



I had never heard of Schaeffer's before two months ago. A buddy of mine has been using it for several years in his CTD based on the recommendation of several large dump truck fleet managers. The fleet managers are completely sold on Schaeffer's. They all said that the usage of oil between changes had all but completely stopped and that their oil analysis reports had never been better. Unfortunately, my buddy has never done any oil analysis so I don't have his reports to check out.



The one thing I noticed immediately after I started using Schaeffer's was that in very cold weather (not plugged in), the engine is considerably quieter after startup than with the Valvoline. In fact, the engine seemed quieter with the Schaeffer's right after a very cold start up than it did with the Valvoline after the engine had warmed up. I was amazed.



We'll see how my next few oil analysis reports stack up against my previous ones...

Now that's what I'm talking about ( in my first post ), anything else is just idle talk.

Now how much better of an endorsment can there be?

A few pics

Here are few pictures under the side cover after 200K + and 6 years of synthetics!

While the oil gets really black (really reallly black), the highest soot reading I have had is . 04%.

I'm running the Rotella T 15w40 in the old CTD, for previously stated reasons but I would like some advise from the group on my Toyota Landcruiser. I normally run Mobil 1 5w30 and it has 125K miles on it. Wife now only drives it around 8K miles per year so I change the oil and filter every 6K miles. When I adjusted the valves at 100K it was very clean with no noticeable wear, but I was wondering if I should start using a heavier weight synthetic since it is getting older and it sits for a few days between trips? I've noticed in these discussions that many of you use 15w40 weight synthetic even in gas engines that call for 5w30. Just wondering why and the benefits

Pit Bull:

In a gasser, there are a couple ways to look at it with synthetics. A synthetic allows you to either 1) run a thinner oil with the same film strength, or 2) run the same grade oil with much greater film strength. What I am saying is that a 5W-30 synthetic is probably as protective as a 10W-40 dino, if not more.



Ultimately, you have to choose where you want to be on the scale of protection vs. economy. A 0W-30 synthetic will have very little friction, and probably give great fuel economy. Meanwhile, a 15W-50 synthetic will give incredible engine protection, but at the cost of fuel economy.



In YOUR case (Landcruiser, 120K+, mostly on synthetic) there's a good chance that the engine clearances have worn little, if any. You could probably run a heavier oil safely, but don't do it thinking that the engine has "loosened up".



I personally would rather lose a little MPG in favor of a more viscous oil that has far greater shear strength (think of bearings and valvetrain).

Hohn, thanks for the response. I have noticed that since the truck sits for 2-3 days between runs it uses 1 qt. of oil in the 6K mile change interval. It never use to use any oil. When it comes to fuel ecomony this SUV is a dog. I get 14-15 mpg on premium. (have to use premium or it pings) . The local hardware store carries Amsoil what weight would anyone recommend? Obviously with the kind of mileage this SUV gets I am after better engine protection versus mileage The best this SUV ever did on mpg is 18 hiway and 16 city on regular in Atlanta (smooth level freeways) when it was new. I think the reason the mileage is poor is weight (4800 lbs) and a small 4. 5 liter 6 cylinder engine.

Sledpuller sez:



"I drive 120 miles or more each day to work. I wanted to extend drains farther than I was on petro. "





THIS is what puzzles me as to the mantra of "extended drain intervals" - and the use of synthetics. You would THINK, based upon what synthetic supporters CONSTANTLY post here relative to synthetics, that the synthetics are the ONLY oils that you can do the extended drain bit with - YET, *I* have in the past, seen several oil studies that clearly indicated that even the dino oils can be used in extended intervals - out to about 32,000 miles with EXCELLENT results...



YET, the syntheitic supporters remain tight-lipped and silent when that is pointed out - WHY?



Sledpuller - did YOU ever try the same extended drain intervals with dino oils and analysis as you have with Amsoil - or did you just assume - as many others seem to - that it's not possible?



Notice, I'm NOT claiming the dino oils will go as FAR as the synthetics, but that they WILL go MUCH farther/longer than what most of us are currently running them... 32,000 miles is a LONG ways for most of us!



I'll hafta try to locate one of those extended frain studies with dino oil, and post it here for general info - and for those who falsely assume extended drains are ONLY for synthetics.



And yeah - *I* could try it on my own truck, but my mileage piles up so slowly, it would take YEARS to develop a meaningful result...

 

[Hohn]

Sounds like you have nothing to lose then, PB. I would not fear running a 40 or even 50wt oil. Try the 40 first. Redline makes a 10w-40 synthetic that has higher film strength than a dino 20w-50.



My Grandpa used to sell Amsoil. I have had good results with it. I just prefer Redline. I see results with Redline in terms of engine smoothness, cleanliness, and economy. I have used Redline in my Maxima for the last 70K (bought w/30K). The car still doesn't use a drop of oil in 10K changes, and it sometimes sees full throttle on a cold engine. It's surgically clean on the inside, and has almost the same power as when new (that was so long ago I don't remember when it was new). I use 10w-30.



I am also considering using their 10w-30 in my truck, since it is CH-4 rated. I would like to only have one kind of oil in my house, but I don't like the idea of a 30wt in the diesel. Maybe I object for no reason, but for now, Delo is in the truck and staying there.



Why do I like synthetics? Why do I pay almost 8 times more for oil? Because it's the best. To me, the arguments of synth saving you money are kinda weak (unless you are talking about an engine that would otherwise not last). I use synoil because it's better at doing what an oil is supposed to do, in every area. I mean, if you had to have a major surgery for a life-threatening condition, and had to chose one of two options, would you choose doctor A (whose practice is considered more than adequate for most people) or doctor B (who is considered one of the world's top 1% experts in his field)? I bet we would choose doctor B, EVEN IF HE COST EIGHT TIMES MORE.



Until using synthetic threatens to put me in the poor house (not far away on my $30K/yr pay), I will continue to use it because it's simply the best. I prefer Redline, but ANY syn (Amsoil, Torco, Neo, Royal Purple, etc. . ) will be better than a dino oil at doing what an oil does.



It's all your choice if you want to pay for it. True, a synthetic might not be 8 Times better than a regular oil, so YOU have to determine its value in your financial priorities.



YMMV

I understand what you all are saying but how do you explain this:



http://www.blackstone-labs.com/newsletter.html



" Many people have very strong loyalties to certain brands of oil. They'll swear by their favorite brand and assure you that anything else is bound to ruin your engine. But we're here to dispel that myth. After nearly 20 years of testing oils from thousands of different engines and industrial machines, we have discovered an interesting fact: it doesn't really matter what brand of oil you use. "





You cant just dismiss what blackstone has determined through thousands of analysis' and decades of doing it.



Agreed that syn oil flows better at extremely low temps (cold startup) and is better at keeping the insides somewhat cleaner but as far as service life what is the advantge? Especially if the Cummins will do ( this has been documented ) million miles without overhaul on dino oil and Mopar filters. Theories and speculation and oil producers advertising aside, the fact remains as Blackstone pointed out. Is there ANY truck that has racked up 1,000,000 miles on < insert brand here > syn oil??? If the answer is no then then any arguement on syn oils superiority is strictly theoretical. (IMHO )



Does anyone using < insert brand here > syn oil have oil analysis numbers that are lower in wear metal numbers than I see using Delo 15W-40? This would be the proof of synoils superority over dino stuff. If you dont see lower wear metal numbers what are you gaining? Unless you are trying to use extended drain intervals to make syn oil cost competetive with dino oil.

 

[Texas Diesel]

These oil threads always end up on the same note:



A percentage useing dino oil

A percentage useing syn oil

One person useing Homers Duck Butter

A couple of people using Crisco



And then Admin locking the thread



How about a new ending for this thread?

 

[Sled Puller]

I have had an e-mail into Blackstone, but my servers emails have been down since Monday. Can't send or recieve.



A different ending?



I decided engine oil is highly overrated, and am draining it as we speak.



No oil, is the best oil, I have decided.



Nobody has tried that yet.

Dave Mitchell endorsing your product.



When we tear mine down next year, maybe I will convert him.



After all, 2 years at 500 hp is just as good as 1 year at a 1000 hp, right? Right?

 

[Gary - K7GLD]

AHHhhhh - let's face it - they're ALL great, and final choice depends largely on the ability of the "salesman" doing the pitch, your personal predjudices and preferences - and how deep yer wallet is...



And I still maintain that MOST users will never wear out the Cummins in their trucks before they either die or trade it off anyway - regardless of WHAT brand/type oil they choose...

Wonder if we still need to change the oil filter then?

"No oil, is the best oil, I have decided.

Well, actually, that HAS been demonstrated MANY times - usually at fairs, flea markets, swap-meets and such... A guy has this engine - either up on a stand or in his demo vehicle, he pours in his magic stuff, runs the engine a bit, then DUMPS out all the oil... He then proceeds to fire up the engine, runs it, dumps dirt in the open valve covers, drains out all the coolent, and the engine just sits there spinning merrily... Great stuff...



Probably an Amsoil derivitive...
