Mobil1 10w-30

 

Other. Redline 5-30 and a KNN filter

 

I used 10w-30 Pennzoil dino juice for 17K. Daily driving and autox. I used Mobil 1 10w-30 once and it made the car sound weird, burned more between oil changes, and sludged up more.

I changed my oil every 2500-3000 miles. With the pennzoil I put in 4 qts, got back 3.5-3.9 qts everytime.

edit:I still use the pennz dino juice, but I am running 5w-20. I've been running NA for the last 23K miles.

 

torco sr-1 5w-30 synthetic

 

brad penn ftw

 

valv vr1 20w50, the mobil 1 gave me smoking issues(older turbo).

 

redline or mobile 1 10-30 for my NA cars and 20-50 for turbo cars

 

castrol non-syn 10w-30 in my turbo motor and all motor setup, I have a question for some of you guys using 20w-50 on your turbo motors, I had smoking issues with 10w-30 castrol gtx non-syn and I ending up trying out that cheap walmart "super tech" oil 20w-50 and the smoking problem went away, so is it better to use 20w-50 in turbo cars rather than 10w-30 all year around? reason I ask is because winter is coming, and I don't wanna run thicker oil if its gonna cause problems.

 

other. valvoline vr1 racing oil 20w-50

 

I run Mobil1 syn 10w30 and change it every other race. After 150 hard passes (10k rpm plus) the bearing still look new.

 

Castrol Syntec 10w30 or 40, can't remember.

 

Other: Shell Rotella T 10w40

 

HONESTLY!! i have been using whatever is around. I broke the motor in on 4 quarts of cheap Shell 10w40...

Then i scored 5 quarts of Royal Purple (car ran a lil rich b4 getting tuned and got some fuel in the good stuff.. what a waste)

Since then i have been running on Castrol 10w40. Havent had one oil related problem.

 

val durablend 10w 30

 

What is the diff in these two? The reg 20w-50 and THE RACE ONLY STUFF?

on top od that they have the SYNTHETIC...? Which do you V users prefer?

 

i like mobil 1

 

brad penn 20w50 their oil is a partial synthetic you really dont want to run a full synthetic oil.

 

This guy speaks the truth! I love this oil. Honestly, if I were NA I would use the German Castrol, but with turbo this is my hands-down favorite. This stuff takes serious abuse.

 

Wow, I have to say I didn't expect this thread to become such a success, lol. Since this I've tried running Royal Purple and although it's working fine, I can't see much of a difference over Mobil 1 to be honest. I guess it would help if I had an oil temp gauge.

 

I RUN ROYAL PURPLE 10W 30 NO ZINC ADDITIVES
