Do you look at the viscosity index value when buying an oil?
http://en.wikipedia.org/wiki/Viscosity_Index

Some VI values:

Castrol SLX 0W30 195
Motul 8100 0W40 187
Mobil 1 0W30 169
Mobil 1 0W40 187
Motul 300V 5W30 162
Motul 300V 5W40 176




I read that the 300V line is a very good racing oil. Is it suitable for street?

I use the motul 8100 5w-30 for regular street driving.

Has anybody used german castrol 0W-30 in thier evos? I would like to know more about it since the guys on the bitog oil forums are saying good things about it.

I only use Castrol SLX 0W30 (german).

Notice that it is the only one 0W30 that meets ACEA A3/B3 = high performance oil, it is API SL and has the highest Viscosity index.

The only thing I do not know is if 0W30 is too thin for the Evo engine.

the german castrol (green) is one of the best oils...the problem here is trying to find some

The green is prety much impossible to find now. I heard the new gold is prety good too.

btw, I read here in the forum to stay away from longlife oils. Why?

They are not true synthetics, they are blends of dino oil and synth. Works fine in my 98 Ford beater but will not get near my Evo.

weird because the SLX is considered as a longlife oil but considered one of the best oils as thisxguy wrote.

Recommended mobil 1 is good enough. But given a choice to use better oil, why not?
