Amsoil Or Redline?? First oil change............

[Archive]

I got close to 6k on the truck and I think Im going to go the Synthetic way. Amsoil says you can double your oil change time. That would be 15k, seems high to me. Or Redline any opinions? Which is better?

Well, I'm probably the only one on this BB that has used both. At 13. 7k mi. I switched to Red Line 15W-40 synthetic (after using Valvoline/Cummins Premium Blue for break-in). At 32. 5k I switched to Amsoil 15W-40 HD Diesel & Marine. At 41. 4k I switched to Amsoil Series 3000 5W-30 HDD.

I was not impressed with the oil analysis results I received on the Red Line (three different oil analyses, the last sample was split and sent to two different labs as I was "sure" my samples were not being tested accurately). Each time, I only had 6k-7k mi. on the oil at drain interval. It pains me to admit this as I've been a long time Red Line customer... and an extremely happy one at that, until I had data that suggested this synthetic was good, but not as good as it should be for what they charge for it. Interestingly enough, the split oil sample came back from both Blackstone and CTC very differently in some categories. Currently, I'm awaiting the analysis results of the Amsoil 15W-40 (from Blackstone). After reading all the positive feedback on the Amsoil Series 3000 5W-30 on this BB (with oil analysis results to back their claims), I switched to what I consider to be the best of the three. Although I have no oil analysis results to prove my point (yet), careful observances have shown positive differences with the use of this oil (i. e. , increased fuel economy, reduced internal friction... based on increased idle speed of 50-70 RPM... which NONE of the other previously used synthetics did).

<font color=blue>Don't switch to synthentic until around 15,000 miles. It depends on how hard you have worked it but its prolly not broke in yet? People switch over anywhere from 10,000 miles to 20,000 miles. If you tow a heavy trailer or on a regular basis then 10,000 should be good.

Ok I will not switch to syntec this oil change i will wait until next change if this is the best. When I switch which is better?

SAE 30 Synthetic Diesel Oil or SAE 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil?

Sky, as John pointed out, the series 3000 5w30 is the prefered oil. Kats point about break in seem to be stressed and is very important, let it break in good before you make the leap. Regards Pete

Hey Sky,

I run the Amsoil 15W40 in my truck. As a matter of fact I have Amsoil in the transmission, transfer case, and both front & rear differentials. You're right not cheap. A lot of people will argue the Cummins will last for 500,000+ miles anyway, why bother with the extra expense. Just because it makes me feel better! I buy a case of the 15W40 oil, and 4 filters. I change the filter and add a quart at 5000 miles, then change oil & filter at 10,000 miles. The 5W30 seems a little better, but, I personally don't feel it's better enough to justify the hefty premium over the 15W40.

Hay Kat? (prolly)Whats that? LOL. See you on the 21st.

Sky,when you change your engine oil,go with the Series 3000# 5W30 in my opinion the best but wait till at least 10,000mi. for total break-in

Sky if your worried about price contact Amsoil and become your own dealer for $20 a year the savings are worth it

Ive been using the mopar 15w 40 since new from the dealer. ALso get the filters from the dealer> after joining this site could not believe how cheap Genos is for the filters. My question is is the factory oil junk? We get pretty cold winters in the east and I didnt want to heavy of an oil. Change oil every 7000 miles.

The engine WILL go for 500,000 on normal oil. But wouldn't it be nice to only have a 100,000 miles of wear on it when you get there?
Also be sure to run Amsoil filters. If you want to, take samples with different filters. I have, and after seeing the results, my extra brand f filters are still on the shelf!
When you factor in all the benefits, Amsoil is less expensive than regular oil.
RedNut,
I would use the word "adequate", not junk, on the factory oil!

Sky, I will post the data when it is made available to me.

Either Mobil Delvac 1 5W-40 or the Series 3000 Amsoil 5W-30 should be just the ticket. I'm a former Mobil 1 fanatic, but it's hard to argue with the higher ratings shown on the bottle + claims being backed up by oil analysis; I'll be switching to the Series 3000 very soon.

Where is the best place to buy amsoil?

Randy J,
Saw your comment about changing filters at 5K intervals and oil at 10K. I run Royal Purple synthetic and change filters at 2500-3000 mile intervals and oil at 12-15K depending on what I've been pulling. Have not been testing the oil and that is why the short intervals on the changes.

Do you have a bypass filter system or just the factory setup. Are the Amsoil filters really that much better than say a Wix or fleetguard? I have been running Wix but have seen several comments about these that is making me consider going to a different type filter.

I just received my oil analysis report from Blackstone Laboratories (switched from Red Line 15W-40 synthetic to Amsoil 15W-40 Heavy-Duty Diesel & Marine synthetic). Although the numbers exhibited a marked improvement between the two oils, what's really interesting is the comment that accompanied the report. The following is a direct quote (my additions for clarification are in brackets): "John; nice improvement. The oil has changed from Red Line to Amsoil and the drop in aluminum and bearings metals is nothing short of remarkable. This oil [Amsoil] was run 8,292 miles, 1,946 miles longer than the last sample [Red Line]. Iron is still read at twice average (see universal avgs) but this metal tends to track with miles use of the oil, and at this use, you can expect high iron normally. Silicon dropped to normal as well. No diesel fuel, moisture or coolant found. Looks okay @ 41,310 mi. " #ad


Notable reductions include: SILICON: Red Line (RL)=20, Amsoil (A)=6; ALUMINUM: (RL)=16, (A)=4; COPPER: (RL)=24, (A)=9; LEAD: (RL)=26, (A)=3.

An interesting side note to this is the use of the K&N OE style flat panel filter with my Air Bulldog induction hood system (i. e. , replacement air box base) throughout the entire oil change interval. Also noteworthy is that both samples submitted were taken exactly the same way, and both used ONLY the Fleetguard LF3894 StrataPore filter (I hadn't added the Amsoil Dual Remote Bypass system yet). My next sample will be with the Amsoil Series 3000 5W-30 Heavy-Duty Diesel synthetic along with the Amsoil Dual Remote Bypass system installed. #ad
The only difference will be the method in which the sample will be taken (I added the Amsoil sampling valve at the remote filter mount). The sample mileage will also be of slightly longer duration. All in all, I'm very pleased with the improvement! #ad

How are y'all taking the oil sample? I was thinking pour some out of the filter, but you would probably get some of the trash back out of it. Should you just back out the drain plug a bit?
