I know it says to use 5w-30 synthetic but mobil one and other 5w-30 kinda burns quick... I used 5w-40 synthetic in my GTI (5w-30 recomended like the cobalt) and it worked great and never even lost an ounce since my next oil change. was wondering if anyone has used 5w-40 synthetic. Let me know please or have any suggestions besides mobil 1 5w-30.

 

i used two quarts of 5w-40 synthetic in my last oil change. I mixed it with 5w-30 becuz pepboys was out. But im currently using Penzoil Full Sythetic Ultra Class and it works great.

 

I just realized it was you P. My dude all you gotta do is ask if you got a question about your ride lol. Im here to help out. I do know cars bro lol. But yea i mixed both and they work perfectly fine.

 

Lol whats up T. Thank you bro, I was sure it will run fine. Just wanted to see some other ppl experience if they put 100% 5w-40 or any other oils for recomendation. We gotta meet up soon man, I need to show you my car.

 

haha definitly bro. I have my catted downpipe i just bought but havent put on yet til i buy my intake and tune it. But yea 5w-40 will work better for the summer itll last alot longer especially in this heat wave we havin around here.

 

hell yea brotha. What intake you going for man? please say KN Short ram. It's flawless and install was a 30 minute job by myself

 

so nobody has anything to say about 5w-40?

 

Doesn't look like anyone here as tried fillin gup with just 5w-40. I wouldn't think it would hurt anything and it might be beneficial in hotter climates.

 

yea same here, I will give it a go then. It didnt hurt my GTI Engine, I think it will be okay with this. I just hate having to check my oil every damn 2 weeks to make sure its not burning up and have to put in half a quart everytime lol.
