What oil do you use
 

thought we may as well talk about oil. Wouldn't be C5 gen if we didn't.


I use Valvoline 5/30 Synthetic. Don't tell the C5 engineer dude on CF. He got nasty with me one day.:confused5:

:dance: Let's dance

Just plain ol' Mobile 1 here. I was going to use something fancy but price won out.

In keeping with the theme, I also use and endorse the following products.

NAPA Gold oil filter.
Amsoil trans fluid.
Valvoline dot4 brake fluid.
Valvoline pwr steering fluid.

I was going to use Mobile 1 but the place I have it changed uses valvoline products. It's on the list of approved oils so I reluctantly said OK.

I do use valvoline on all my others vehicles and have for years with zero issues.

Mobile 1 Extended through a NAPA Gold filter

Mobile 1....I would do it myself, but the dealership does it, and tops off all my other fluids for $60.00...so I let someone who has a lift work under the car...LOL

60 bucks? They charge me 85. I'm thinking of doing it myself though but I have to buy some new ramps.

I have a coupon book. :D



(In all fairness, it did go up, and last time it was like $67)

I've used Mobil 1 exclusively, but am seriously considering Royal Purple next time.

whatever the dealership puts in it :D

15W-50 Mobil 1..........I like the $24.50 5-quart jug price at Wally world but more the 1,300 ppm Zinc (Zn) and 1200 ppm Phosphorus (P) content that are for the needed anti-wear protection to critical engine parts, such as piston/cylinder walls, roller cams under heavy valve spring pressure and especially those that employ a solid “flat tappet” type system.
I drive ALL my vehicles hard and they haven't let me down so the current PPM above are very high compared to the other off the shelfs/price per quart :D

I know a lot of people swear by Royal Purple.

My valvoline did extremely well but from these tests I may be switching to Royal Purple as well.

When you read test reports from one site to another, there seems to be a big differance from one mfg, to another. whats up?, no one can come up with the same resaults. So, use what you feel good about, just chang your oil & filter.
GM says to use Mobil 5w30, :beat:

Try using KY......it's slicker than hell......:rofl:

Hey Jonathan,good to see you here buddy!

Yeah man!

I buy the Mobil 1 and ACDelco filter and bring it to dealer...they change it dispose of old oil and check everything else....$16.00. Mobil 1 is much cheaper at WalMart and Costco then at dealer !
