Let's talk about oil. . . What do you use?

[2dr_sedan]

What size motor, and what do you use? Seems like with oil technology, not alot of SAE30, SAE-40 used much these days, lots of blends.
What works for you?

Whatever is on sale.................

[Nick Flores]

I use recycled dinosaurs...

[Dog Dish Deluxe]

I use Valvoline straight 30 wt. with zddp additive. Seems to work. I lost a motor or possibly two motors on synthetic, so fuk that jive.

[racer-x]

lucas oil 50 wt in the hemi its by far the best

[Orlando1701]

I just got my car three weeks ago and the oil hadn't been changed in years... so right now I'm running 20W-50 to clean the engine out.

[Waddayacare]

15w50 Mobil 1 in an Oddy's 408 sbc

[RopeSeals???]

Synthetic 5W-30 or 10W-30 depending on OAT, although I did have some problems with MAF contamination. Switched back to Mineral and no more issues...

Valvoline VR 20W-50 for break in

[GassersGarage]

I run Valvoline Racing 20/50 in all my motors.

[Master of None]

I just switched to Brad Penn 10-40 in my 289 Ford. Was running Napa brand stuff because I was changing oil often due to sticky lifters. The Brad Penn seems to keep the lifters quieter.....could just be in my head too.

I use 5-w30 quakerstate high mileage. And 0-w40 when I can find it.

[terrarodder]

Bard Penn, has zinc in it.

[Diavolo]

I use full synthetic in everything and the lightest weight I can use and still have oil pressure. I spent some time reading http://www.bobistheoilguy.com/ and have become a believer in his practices. My DD OT vehicle now has 160K on it and is still running strong. As for synthetic oil killing a motor, I call BS. With all the things that could go wrong, synthetic oil is the last thing to blame.

FYI, the ONLY reasons I use synthetic instead of dino is that it flows better in extreme cold than dino oil. Also, more miles between oil changes since it doesn't break down like dino oil. Other than that, no harm in running dino.

I find it interesting that my Ducati and my BMW superbikes are delivered from the dealer with full synthetic and only recommend synthetic to be used in their engines. Synthetic is so bad for your engines, lol.

yep, been using it for years and I run my stuff pretty hard. I also noticed years ago in a Ford I had that used oil, when I went to VR1 20-50 it used less than 1/2 the amount in the same miles and I used straight 60 in my Harley for 20 years . Good stuff

[iammarvin]

Whatever is at Costco. Gotta be better than anything from the good ol days.

[Lobucrod]

Castrol 5-20 in the old lady's 300C. Valvoline 20-50 in the Nailhead. Seems to keep the pistons from swapping holes. 10-30 Q-state in the pickup. Wix filters in em all.

[StayFrosty]

I run the house brand diesel 10w30 from my local tractor supply store. It still has zinc and it can be bought in 2 gal jugs.

[1950Effie]

Valvoline 20w-50 racing with Napa Gold filter.

[Sting Ray]

In my ls3 motor Mobil 1 5w-30 which is factory fill. Everything else, 10w-40 Quaker State, Castrol or whatever.

[eugene vik]

diesel 10 30 sometimes with a bottle of STP for zinc and usually a additve to dissapate heat faster, as most of my stuff has tendancy to run hot

usually carry 15-40 diesel to add
