Help with oil confusion
 

Want to change oil & filter next week. It's the first one I've done since I got the car. My confusion is what oil to use, the book says 10W30 / 10W40 for the temps we get in this country. But some on here are using different such as 10W50. I've always gone with what the book says but people are using different, I'm a bit confused:confused::wonder:

what tems does your oil get up to?, standard engine? track work?

Daily driving / No track driving

Un-modded and std driving then go by the book.

10w 40 will be fine.

10W40 it is then:thumb:
Now which one:lol1:
Found this but seems very cheap -

Opie will offer good advise.

I would stick with a decent fully synthetic oil. I recommend Millers to all and sundry it's award winning, uses cutting edge technology and it's an English company. It's a bit dearer than the run of mill stuff but then quality does cost a bit more.

So not go with semi synthetic such as this-

The only thing with the fully synthetic it says for competition -

For your car a fully synthetic is the one to go for. The sti engine is in quite a high state of tune even in standard form. Fully synthetic oil will give more protection and operate effectively at higher engine temps.

Ok, thanks for the advice mate:thumb:, I'll go with the fully synthetic.
