Recommemded Oil
 

Hi Guys,
Newbie here, had a look for an answer but still undecided, recently bought a 2007 wrx with some mods such as sti turbo, bigger injectors and fuel pump. Have 120,000ks on the clock, due for my first oil change, subaru recommends 5w30 and i know the genuine stuff is Castrol Edge. I spoke to S&J and they recommended ULX110 10w30. If i was to go with Castrol Edge, what subaru recommends, id be more inclined to go with a 10w30 rather than a 5w30 as i think thats too thin. What do you guys run? Anyone tried ULX110?
Thanks in advance.

Well I am a Redline fan so that is the brand I recommend.

ULX, a new name to me so I looked it up.
Claimed to use a non-synthetic base, curious.
I see from the site that ULX110 do 5w30 as well as 10w30.

Choosing 5w or 10w- depends on your climate and especially on cold start conditions.
If you keep your car in a garage and do not start it early on cold mornings then 10w is ok.
If you do a lot of cold starts, then go for 5w over 10w.
If Subaru recommend 5w30 for your area, then use 5w30 rather than 10w30.

Very clever marketing

Gets to the population hey !

I use 10/60 Castrol Edge in my tarmac car...for what it's worth...

If it's just a street car use the recommended oil. If it's a track car speak with S & J about it. I drove my betty 2 - 3 days a week and tracked it once a month for four years on castrol egde 5w/30. Oil always held up well, was only sprint racing and drags though.
