Observations with synthetic oil

[SnoKing]

I have a story/lesson going the other direction. In the early 80's I purchased a 1976 Chevy K-20 that had about 70K+ miles on it. The seller said it have Mobil 1 in it. It burned oil and after a couple years I pulled the heads off the 350 and took them in thinking it was valve glides and seals. Nope they said the heads were fine. So I took them back home and put them back on a block that still showed the original honing in the cylinder walls, as I did not want to go deeper into it just then. A year or two passed and I pulled the engine, ran a ball hone in the cylinders and lightly used a ridge reamer on it, installed new rings and put it back together. Broke it in again and no more oil consumption. So I believe the lesson is the original owner switched it to Mobil 1 to early, and the OEM rings never seated.

I had to add a gallon of oil to my '00 Freightliner when it was around -30* outside... The Delo 15W40 was pouring out of the jug like molasses and I even had to hop back into my pickup to warm my fingers while the funnel was draining!! Several minutes to add a gallon got me thinking.

The worst part is the old Detroit 60 Series cracks off at high idle, and I'm pretty sure the oil filter bypass is open for quite a while when its that cold!!!

The 350 8V71 in the Titan 90 Chevy I drove for 3 years used oil like the old alcoholic uncle everyone has in their family, puking some of it and burning the remainder.

That is how you start the "oil war"

Been quiet lately.

I damaged a couple of old Cummins engines back in the day with thick oil and cold temps. Now when someone walks by with an ice cream cone I plug my stuff in

Thanks!! I'll just have to remember this thread, so I can copy and paste the next time I need it lol!! I know there's a keyboard shortcut, but I have no clue how to find it without Google.

 

[fest3er]

On Linux, the ° symbol is created via <RIGHT-MENU> o o, pressed/released in sequence. Similar for ™ (<RM> t m) and © (<RM> o c), résumé (<RM> ' e), würst (<RM> " u), el niño (<RM ~ n), and como ça va (<RM> , c), € (<RM> = e), — [emdash] (<RM> - - -) ± (<RM> + -), Æsop's Fables (<RM> A E), Scheiß (<RM> s s) and many others.

Search for "macos symbol shortcuts". Windows seems to generally require one to memorize a large table of numbers.

Awesome, I never knew this, thanks!

 

[MarkEagleUSA]

Character Map with display the key sequence to enter special characters from the keyboard (if you can remember them).

 

[AH64ID]

Alt-248 will give you the °
Alt-241 will give you ±
Alt-230 will give you µ

You have to use a number pad, not the numbers at the top of the keyboard.

or just pin the character map to the tool bar below ↓ then it is always there √

Speaking of synthetic oils....this is a new one to me.

Most of you probably know I'm a little skeptical....but am interested in your observations/opinions. They've been around a long time, not as long as Schaeffer's but a long time none the less.

Very interesting.

150,000 miles in the 2,000 hour interval would be a 75 mph average

I can't seem to find a data sheet on the oil, but the website is not the best.

Their oil filter does have some pretty good specs thou.

LOL, that would be something. I interpreted it as "up to" one or the other, whichever occurs first.

It's funny though, they claim less than a penny a mile operating cost but fail to say over how many miles....
Over the 150,000 miles at a penny a mile they claim that's ummm, astronomical!

Yeah it should be whichever occurs first, which is why the 150K miles isn't obtainable on a diesel. Even on a gas engine at 3,000 hours that's a difficult to obtain 50 mph average.

You underpowered guys are always talking about how stiff your springs are.
