What kind of oil are you running?

[DynastyLCD]

Rotella T 15w40. high zinc content = awesome for engine parts. 15k later and my cyl head looks like the day i had it planed/cleaned.

 

[3rdstrikedsm]

Come on guys, can't we settle on something here! How the heck am I supposed to decide what to run if everybody is running different brands and weights!

 

[JSchleim18]

Honestly, for the money and performance, I'd go with Brad Penn. That's why I bought it.

 

[4thStroke]

^Exactly.

It's less than $6.00 a quart, is a semi synthetic, and has a healthy amount of zinc and phosphorus.

I've talked with a local cam grinder who can't say enough good about it.

I made the switch from Mobil 1 0w-40 to Rotella T6 5w-40 for summer. Gas mileage is pretty comparable and over on bitog the new and used oil analysis are very impressive.

UOA Rotella T6

VOA of Rotella T6 for Reference

Reason I made the switch at least for summer is the fact that Mobil 1 0w-40 tends to sheer to a 30w. While it isn't a big deal in the winter my oil pressures tend to get a little lower then I'd like when I'm beating on the car during the summer. Rotella T6 seems to keep its viscosity better. It also has a couple hundred ppm zddp which is nice.

I will be looking into this.....I am on stock internals though. Well 2G pistons but that is still stock.

 

[turbofonz]

Mobil 1 10w30 in my Talon for the 50k hard miles I put on it, head is still SPOTLESS inside. I like the fact that it's $23.50 a gallon at walmart too.

VR-4 gets Rotella 15w40 which I also am a huge fan of.

 

[Rausch]

Castrol TMS 10w60 /ubbthreads/images/graemlins/smile.gif (Not in the garrant tho)


I always ran Mobil 1 or Castrol 5/10-30 in the Galant, depending on the season. Never an issue, and lifters were pretty much silent with the 10-30. (original lifters)

 

[PreskitVR4]

I would prolly run Brad Penn if it was more redily available in my area, Rotella is KFA, and its avail everywhere. My local O'Rielly has 1 gal. jugs of T6 for $17.99!

 

[Galantvr41062]

Brad Penn or any non detergent motor oil with a high zinc content will have rave reviews from v8 or other domestic shops. Back in the day I heard about Rotella T 10w40, but I use that in my diesel. I have used Mobil 1 but when I daily drove my Talon with a built motor I used Castrol full synthetic 20w50. When I build a motor I like to use a new filter and 30w oil and let it warm up, then change out the oil and filter to 30w non detergent with Comp cams break in stuff, that has a lot of zinc in it. If you use oil with detergent and the zinc additive they are fighting for the same space at a molecular level and its less effective. And for dyno tuning or racing down the strip or on the street with my race motor I use Redline race oil either 30w or 40w. And if I were to street drive a motor for more then 5000miles between tear downs then Castrol 10w30 or 20w50 full synthetic will be my choice.

Valvoline VR-1 20w-50.

Wanted to throw that out there to screw up the standings thus far.

[GSX_TC]

Lol dam I thought I was gonna be the only one, I also run Valvoline VR1 racing 20-50 in all 3 of my cars. Love it. Might switch to that rotella 15-40 though

 

[vr4hotness]

10w30 here in socal.

 

[Lancer99]

Ive been using 5w30 from M1. Is 5w30 to light? I notice everyone is using like 10w30. I've been using just because thats what other people have told to use is 5w30. I never really had the chance to sit down and read the differences between them. So what should I use when I get my new motor in and in the t case and diffs?
