Hi all!
This is my firts post in this fantastic forum. I write from Europe and I would like to increase my knowledges on lubricants and so...
I have been reading long this forum and I would like you to help me choosing the best motor oil lubricant for my aplication.
I own MY03 European Impreza STi (2.0l turbo, 265 bhp stock)that would have in few weeks a turboback system, sport air filter and a reflash (~330 bhp expected). I come from a "thick-is-better" comunity, but after reading and learning (?) a lot I think I have surpassed it.
By the moment I have been useing Mobil1 with Supersynth 5w-50. First change done with 2.000 miles, the next two at 5.000 miles (each one).
The climate where I live is not too hot nor too cold, in spite of the track days can even be with very high temps even 35-40cº ambient temp(its a different area).
The car is a daily driver (at least 70 highway miles every day, usually very softly driven here, around 3000 rpm´s), with few tracks days during the year, and its also hardly driven often.
I would like to advance to a 0w-30 (the "prefered" is a 5w-30 according to the manual)as long as I can buy here the Castrol SLX 0w-30 (wich I asume that is the GC
) but here is quite expensive (88$ 4 liters) and I would like to know if there are other options.
Please note that the M1 0w-30 Racing is not available in Europe. Whould the standar M1 0w-30 be recomendable? or the Castrol RS 0w-40? any other? Would be woth it to buy the M1 R to USA? is it api aproved (I want to keep the warranty)?
Whould be the oil comsumption higher on a 0w-30? can be the oil change intervals be extended?
Thanks in advice!
