Don't over think this. If the oil meets the manufacture requirements it's ok to use for the engine.

 

IMO people make way to much out of this. Just go buy any name brand oil that meets the spec's for the engine. The over all differences are so small you'll never notice.

 

You should be more conserned about the flaw in the OEM tune that causes detenation then which oil you use. Tuners have found the flaw and can fix it with there own maps. That will reduce cylinder pressure and save the bearings and the valves. But that's just my opinion.

Do you know if the map in the OTS map for stage I on the COBB Access Port addresses this?

I'm getting a headache.

I am anal when it comes to oil changes. I change my oil every 4000 Kilometres/2500 miles or three months, which ever comes first. The three month OCI usually covers me for the seasonal change in weather. Maybe it's a little extreme but changing the oil is one of the best things you can do for your car. ESPECIALLY if it has a turbo.

As far as name brand goes, I have NO idea who makes the claimed best. I've heard great things about RedLine and Royal Purple. A far as all the 'run of the mill' oils go like Castrol, Pennzoil etc; my head is as far up my ass as it possibly can be when it comes to my knowledge on brand names. So this is where I can use some help.

Boxer engines use more oil then conventional engines so one of the questions should be which oil does this car 'eat' the least amount of? And with OCI of 4000 Kilometres/2500 miles, it's probably not a concern.
