Engine oil

[iain85]

After some advice please chaps.

So I was advised to use 5-40w engine oil on scoobynet, but today after going to Halfords the guide said magnatech 5-30w fully synthetic. I checked with the advisor and he looked on his computer and said it was correct so I went with the 5-30w.
Should I stick with this? Bog standard 2004 wrx if it makes a difference.

Cheers in advance,

Iain

i was told the same but i think 5-30 is to thin so ive alwase used 5-40 fs

Don't want to damage my new pride and joy. Too thin you say?

[harvey05]

most cars run 5-40 or 10-40 but my van runs 5-30 and its very very thin cant go wrong with 5-40 and my misses drives here car like she stole it and ive never had any trouble

far better oils out there for the cost of Magnatec.................not personally a fan of it at all

you'd be better with a 5w40 as above

I'm sure the Subaru book says 5w30 in the service information, yet when i had my scoob serviced by a main dealer (admitted just after i bought it) they used 10w40 instead.

Right, il take it back and swap it for the 5-40 w . Cheers
