Your favorite motor oil?

FYI, Jiffy Lube uses Amsoil.

I cannot find anything to support this claim. The only info presented is that Jiffy Lube uses Penzoil.

I can take a photo of the Jiffy Lube down the block with the huge Amsoil banner over each of their bays.

Maybe just this branch uses it?

Woody,

Ole Wives tale is Castrol would prevent proper breaking in of the new or rebuilt engine. Rings wouldnt seat correctly or something. After engine was broken in it was fine to use Castrol.

Speaking of Castrol, this past Sunday I was working the course at the SCCA autocross when the junior karts were running. They were putting out a distinctive odor that brought back memories of sports car races in the 50s and 60s. At that time the popular oil for the racers was a Castrol product that contained castor oil (thus the brand name I assume). It turns out this castor oil is still popular for the karts. I was also told is is considered carcinogenic.
There used to be a company that sold LP records with recordings of races and engines revving in the pits. Sounds of Sebring was one popular title. The record were sold through mail order and you could pay extra for a small can of the Castrol castor oil to heat in a pan on the stove while you listened to the cars.

I love the smell of 2-stroke oil in the morning! It smells like racing!

I used to think there was no better aroma in the morning then the smell of warm engines and gearboxes, hot brakes and clutches and tires at operating temps.

Now its the smell of sheep, sheep poop and damp collies in the morning.
And a mason jar of Virginia's best corn liqour untaxed of course.

Yeah there is one smell that beats them both but this board allows minors right!

Woody some posters dont know what an LP is or a turntable.

Linn Sondek rules.

To me it smells like yard work.

Since OG Racing carries it, I've used Red Line oil in my engine for years now. I use 10W40 all year, and change it every 6 months (about 10K miles) at RRT's recommendation. I've had no leaks, it hardly burns oil at all, and the car gets revved to "red line" daily. I take it for granted so much now, that I have to remind myself to check it occasionally.

Ugh. The Castor oil has its own unique smell.

I use Amsoil Racing Synthetic 20W50 for the 8 and BMW/Castrol 5W30 for the Z3. Used to use Mobil 1 15W50 on the 8 before.

Anyone use Motul oils here? I like their Brake Fluid, but never used their Motor oil.

[mcoupemindy]

I've been quite happy running Mobil 1.

But, I'm anal about it ... 5K and it's out.

[JC5]

Seems like 5,000 miles is about the adverage amount of miles people are changing their oil.

I'm using Motul (8100 E Tech?) in my M Coupe at the suggestion of RRT. It costs around ~$10. Is it good? How would I know? First time I've used a synthetic.

[Jase007]

Mobil1 0W40 in my 528iT for BMW LL01 but, I change it every 4-5K or so.

Have run Valvoline dinosaur in my E30s ... one of them using it for about 200,000 miles now. Good results after 15+ years ... so far.

Brad Penn Racing in on-track P-cars as well as Valvoline Racing 20w-50 ... but think that will be changing to Swepco motor oil [for flat tappet engines : non-hydraulic) b/c even Valvoline Race has reduced friction modifiers ...

See www.bobistheoilguy.com

And good tech info from Charles N at his site: www.LNEngineering.com

Oil is the "life blood" for air / oil cooled motors ....

I've been using Valvoline Racing 20W50 in my M3 since I bought it 11 years ago (and the previous owner did too). I replaced the rod bearings as a precaution at 162,700 miles (Sept 2006). They were fine and the nationally known tech said the engine inards were clean as a whistle.
