Anyway; here's what I'm gonna let you people help me decide:

World Products suggest you use a rather thick engine oil for their ManOwar blocks, which I'm running. 20W-50 is on their list.

As I used 5W-50 motorsport last season and experience quite low oil pressure hot & idling and 0 oil pressure in 360 deg turns, I was going to change to 20-50.

Thing is: You only find 20W-50 mineral oil? Have not been able to find any synthetic or blend.
Mind you; I'm in Norway- not the US or central Europe...

We have Shell, Mobil, Agip, Castrol, Valvoline, Comma and a few other brands here.

So, should I go with a 20W-50 mineral or what?

I have found some reference to, I think it was Mobil 25W-50 Motorsport oil... Anyone familiar with this?

Racing season is here now, and I'm installing an accusump, a gear oil pump/cooler in addition to new roll cage, new seats, new harness and a new brake- box with proportioning mechanism and front/ rear mastercylinders.

I'm excited!

Happy springtime, everyone.

Hi,

Personally, I use 10W-40W GTX. I feel the real key is how your engine is used and how often you change the oil. Most all of my vehicles have gone well over the 100K mark with petroleum based oils. I subscribe to the sever duty cycle or every 3K miles, or so with changes before and after winter storage.
I have nothing against the use of synthetic, I just feel it's a matter of recognizing your engine's needs and doing the right maintenance.
PlaySafe!
