This is what my friend (he works at Pennzoil) put in my car.

He seems to think it's a good idea. Are there any pros or cons?

It's "summer" here now but not all that warm yet. I do mostly a mixed bag of driving. Drive 30km to and from for work (all highway) 2-3 times a week. The rest are all 5-15km trips. I Hit VTEC and redline almost EVERY time i'm in the car.

 

don't see why not. 5w will flow better than a 10w anyways. i wouldn't worry at all about it, as long as your motor isn't consuming a whole lot, which would warrant a weight up in oil.

 

50 weight is really thick..... might want to stick with a 30 weight.

 

are you sure about that?

 

so does anybosy know for sure if this is ok to use
if it's safe and actually better?

 

better than 5w 30 synthetic mobil1
that's what i use and would it be better to use the 5w50
is that oik thicker
does anybody have experience with this viscosity?

 

The reason that I use this is because it's free! Just wanted to make sure about the oil...
