I herd alot of people running full synthetic Mobil one oil in there boosted setups...Anyone ever run high millage?? is it better? Worse??

I know its basically the same price, this is why im asking..

 

I'm actually not running synthetic in my boosted b20.. But i will say i will be changing my oil once a month. Right now i'm running valvoline conventional

 

How many miles does your engine have on it? That would determine if you needed to run high mileage.. I've ran valvoline maxlife synthetic in some of my older n/a setup's. (50k+ miles)

 

My motor had about 60k on it when it was rebuilt with je pistons and eagle rods, its got arp head studs as well. 9:1 comp ratio running it at 16psi. Head is stock...motor has around 5-7k on it since the rebuild. The guy who built it said to run valvaline conventional as well when i bought it from him. I used it all last year but everyones telling me to go synthetic...im soo lost haha.
