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

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.................

 

I use recycled dinosaurs...

 

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.

 

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

 

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.

 

15w50 Mobil 1 in an Oddy's 408 sbc

 

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

 

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

 

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.

 

Bard Penn, has zinc in it.

 

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

 

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

 

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.

 

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.

 

Valvoline 20w-50 racing with Napa Gold filter.

 

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

 

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

 

Mobil 5/30w in my SBC 427.

It likes to rev and I feel it's worth the cost.
I run a Canton external filter as well.

 

I used that for years in all my dailys, a great all around oil.

I've never tried synthetic. I've read that it tends to find leaks more so than dino oil.
Any feed back on this? I have a Studebaker, and from what I've heard, they even
leaked on the showroom floors when they were new.
...

 

you read right: I've read that it tends to find leaks more so than dino oil.
That is my findings.

 

Rotella diesel in anything that has non-roller lifters for me, but what do I know......

 

I've been running Pennzoil 10w30 with Rislone ZDDP additive in my '56 Pontiac. No problems related to the oil that I know of.
Regarding the diesel oil, and 20w50, and the others how important is it to stick with what the factory mandated as far as viscosity? What is different about diesel oil to make it specifically for diesel engines (aside from the label)?

 

Nothing but Valvoline racing 20/50 in anything I care about! Lost two expensive custom flat tapet cams to regular SEA10/40 before the real world was explained to me. Went right back to racing 20/50. The rest of the fleet runs Casterol GTX20/50. I wouldn't pour a synthetic into my worst enemy's car...

 

Getting ready to change the oil in my 54. I wanted to get straight 20is weight per original spec's but I ended up getting 5W-20 because that's what I could buy in town.
Being a partial pressurized engine with no filter I'm going to run what's spec'd.

Oh, and some zinc.

 

rotella 15 40 in everything gas and diesel

 

Castrol 10/40 for years. Valvoline before that
