I currently have an H22A with 10-30 synthetic (soon)with a Precision SC 44 turbo. I wanted to know if 15W-50 synthetic will be safe to run cuz I have some oil consumption problems right now. Thanks. Obviously this is only temporary until the rebuild happens.

 

i use that in my accord. go ahead, it works.

 

when in installed my turbo I put some in, So far I really like it My oil presure stays more consistant, and I haven't lost any oil yet, my car now holds oil better than it did stock with 5w/30

 

Its probably a better idea to run the 15w/50 (mobil 1 is probably what you are thinking of) because most turbo honda guys DON'T run oil coolers. The heavier stuff has a higher flash point and handles temerature in general better.

 

where do you live and what is the climate like? you always have the option of running a straight single weight oil if you don't need the multi-viscosity. the smaller the difference between the ratings, the better. i.e. 10w30 would have a difference of 20 rather than 0w40 which has a difference of 40. i believe it's due to the extra additives needed to make it a multi-viscosity which we don't want in our situation.

The newer multi weight synthetics last plenty long.

I am american living in England. Anyways the climate is pretty cool, and very rainy. It never really gets hot, but it doesnt get extremely cold either.

yes. All I run is mobil 1. Love the stuff. Thanks again everyone. I figured it would be fine, but u know had to ask. Dont have alot of experience with turbo cars. I am an NA guy converted to forced induction!

 

I only run the 15w/50 in the summer (above 70 allmost every day). The 10w/30 seems more appropriate for you (32-70 degree climate). In sum 32 degree weather lots of motors like the 5w/30 for overall starting and oil pressure when driving. Cold starting causes a LOT of wear and thats why a single weight oil is never recomended by manufacturers anymore.

It also has a LOT to do with how "tight" your motor is assembled. Their are a ton of factors, maybe you should just start reading:
