pretty simple question really, theyre seems to be so much discussion of different oils on this site it hard to get a straight answer lol...

Car is a pretty much standard 2003 WRX blob. Should i go for some 5w30 or 10w40. Doesnt do huge amounts of miles but i like to enjoy it i between driving to work. Will be replaced with a fully synthetic oil.

Regards,

Andy

How many k's have you done?

I'd go with 10w40, I actually use 10w60 but it's a little warmer down in Australia

my car is the same yeah and same mileage. in the summer i use 10/40 because of the weather being hotter. and now my car was ready for another oil change, i've now put 5/30 in it for the winter. i think next i'll stick with 10/40 next time. there's only about 10psi different in oil pressure when its hot

Yeh, i know the manual says 5w30 but most people on here dont seem to go that thin, so 10w40 seemed like a all rounder.

we put 10-40 in 90% of the subarus that come in to the garge would stick with that mate =]

shell helix ultra 5W40 or redline 5W40

All depends on your analocity!

Shell Helix Ultra 5W-40 is very thin at operating temp, almost a 30 weight.

OOPS! Am I exposing my analocity?????


Go for a semi-synthetic 10W-40. Valvoline oils are very trustworthy, but Liqui-Moly, Mobil, Castrol...will do too.

Semi synth? Yep, based on the info you have given here.
