What oil to run

[sparky4017]

OK guys i know everybody has a opinion but what is the best oil for a 95000 mile
motor better yet what oil do you run

[ERAU944]

in my '84 944, i personally run castrol gtx 20w50 down here in florida. i've been running it since 2001, from 68k miles at purchase to 105k miles right now. she seems to be doing all right on dino, and i just can't bring myself to bother switching to synthetic.

I have been using Mobil 1 15-50 and add zddp myself from LR. I will be switching to Amsoil on my next change however (and add zddp) or use the race oil with it in it. I'll see how that goes. my car has 130K and a lot have been on the track.

[sparky4017]

My car is just a weekend driver so it sets most of the time maybe 3000 miles a year that was
my only thought on oil

[mikeran]

Have 202K on mine also run castrol gtx 20w50 and recommend it alot. Helps keep nice oil pressure even in a tired Engine.

+1^
Castrol GTX 20-50
Change the oil and filter every 3 or 4 thousand miles
No oil leaks on FOES-front of engine seals-- in over 13 years on both cars
AZ summer temps are over 100 degrees for 4 to 5 months

Redline 20W50.

Picked a case up on ebay for $72 shipped. Cheaper then Mobil 1 (at that price!) and supposedly better.

[matty89]

20w50 castrol gtx it was 30$ for the 8.8 liters lol! you need 6.5

[racer]

15w-50 or 20w-50 in the summer and 10w-40 in the winter.

I am sure Ernie, or someone else can post the ownersmanual page with the oil viscosity preferences.

Oh gawd, am I actually participating in an oil thread?

Valvoline VR-1 20-50 and a Mahle filter from Pelican. I'll also run Hastings or Baldwin without hesitation. Got the VR-1 because it was convenient and has the ZDDP. I'd really rather be running a 10-40

[VINMAN]

any name brand 20/50 Usually use Castrol GTX

I also run 15/40 Diesel oil, such as Rotella t or Chevron

I want one of those in my back yard

Seems some have had problems with seals going from Dino to synthetic.

[AA_Ezra]

I started running Mobile 1 10w-30 then went to Penzoil platinum 10w-30. Then recently i have been running Shell Rotella 10w-30(40)? it's cheap and is a great oil.

I'm going to give valvoline vr1 20w-50 a try here in the summer and see how it works out.

[Dimi 944]

My car is dedicated for track use and I put Brad Penn 20W50 racing oil.
I used to put Mobil 1 15W50 full synthetic when I was driving it on the road. It has 96000 miles on it.

So has the "what oil should I use?" Topic.

[phoenix_iii]

0w-40 or 5w-40 in winter works (flows well when cold)

10w-50 or 15w-50 for summer is good. If it's super hot out 20w I suppose...?
