What kind of oil do you use?

[98redaurora]

Hello all!!

Just changed the oil in my Aurora, used Pennzoil Platinum Full Synthetic 10W-30 w/ Purolator Classic filter. What do you guys run? Just curious!

Edit: I screwed up and wrote 5W instead of 10W

[renaldo0613]

I use 10W-30 valvoline sythetic blend, with a jug of lucas, and AC delco filter

Valvoline Max life 10w30 (syn blend), mine holds 8 quarts.

Ditto that for me. I ran Valvoline 10w30 full synthetic in mine until I hit 75K, then switched to Valvoline max life. I'm running 5w30 on this oil chance since its so cold here, just in case.

Always delco filters. No Fram BS for me. ;D

Castrol GTX 5W-30. Pennzoil 5W-30 from time to time. Delco PF-61E filter.

Mobil1, mainly for thermal breakdown protection in the event of running hot. I change the filter whenever the DIC says change oil, and I change the oil about every 10,000 miles.

Schaeffer's has 2 friction modifiers. Molybdenum disulfide and their patented Penetro. I've tested both individually on a friction test, awesome stuff. Prevent wear on start up. It's sorta like having a chromoly plating on your bearings Molybdenum disulfide has like 250,000 psi shear strength IIRC
EDIT: 500,000 psi via Bobistheoilguy

I use 5w30 and add a pint of Moly oil treatment for a little added thickness and protection. ;D

Whatever has a rebate 10W30 and PF61 (not E) or Purolator.

Different brands but always 5-30, fully synthetic, no junk oil, only oil that is approved by the GM with the correct specifications.
I change twice a year on all vehicles. Filter must also be approved by the GM.
In my youth (!) I had an old Volvo 121 and I mounted a cheap filter of less good quality.
300 meters asphalt and the car underneath was oiled, the filter was not tight after awhile.
The lessons provide knowledge!

Mobil-1 full synthetic, usually ac delco filter, i change it when the dic says, usually equates to 2x per year although I'm sure i could go way longer

[nelson480]

Maxlife 10-40 in both cars... Whatever the cheapest fram filter there is available.
1999- every 3k oil and filter change
2003- every 5k oil and filter change

[mjwalcott]

Havoline 10w-30, with AC Delco Filter. the next oil change is going to be some type of high mileage, how does lucas work with our engines

[sall]

Valvoline Maxlife 10w-30 with Wix or ACDelco filter.

I have seen the PF61E. The PF61E is new OE design... why not use it?

What do you mean?? The engine oil?? Or the stabilizer?? I have only used the stabilizer. It just makes the oil thicker, amd if you have any lifters chattering when iys awfully cold outside, then the stabilizer will work great.

Find a Molybdenum additive, way better than Lucas. Since it also is a friction modifier and Lucas prevents it from working. (I friction tested pretty much every oil, oils work fine when they have pressure but there is the most friction at start up(no oil pressure))
Lucas had about 1/3 the friction of engine oils, Moly had about 1/100.
Check them out. I think Royal Purple also has Moly Additive You can get pure moly as additive though like 8 bucks.

Every since I checked them out, I haven't bought any other brand. I use their 2 stroke mix too.

i fill up with 6 1/2"quarts of Valvoline Max life synthetic blend then top off with 1 bottle of lucas heavy duty oil stabilizer 32oz.

Since buying my car last May, ran Valvoline Max life 10W-30 in the summer and now 5W-30 GM dealer bulk fill for the winter. Change about every 5K when the DIC drops below 20%.

[oldsAURORAmobile]

I'm a big believer in Max-Life too. I've used it since it came out and it has cured my old smokers/leakers of their bad habits.

Ford's new motor's have moly coated pistons (super awesome!), they ran it through a stress test equivalent to like 200k miles (Can't remember exact #) but they tore it down in front of a crowd and the pistons still looked brand new. There wasn't really any wear at all, it was on a dyno stress test. That's why I like moly stuff (esp Schaeffer's moly grease, or any brand really).

[adamconant]

I also use Pennzoil Platinum Full Synthetic 10W-30 w/ Purolator Classic filter

[kyngofpop]

The cheapest one on sale. Gotten me this far, aint gonna switch it up.

I believe you lol. I've been thinking about switching to Supertech as well. Not full synthetic tho, the blend will do me justice. It's much cheaper, and i know a couple of guys (personally) that have been running it in there N* for years with no problems, or lack of performance issues. Ive always ran Valvoline Max 10W-40 synthetic blend during summer, and 10W-30 in the winter.
