As SupaTouring would say... Dave: A good semi synthetic will do, just don't use Castrol Edge. I use Mobil-1 though *grabs a bottle of Penrite HPR over Mobil-1* Dave: Yep, Penrite HPR isn't bad *Dave's eyes linger over to the shelves holding Mobil-1* Me: *puts 2 and 2 together, sighs* *I wander over to the shelf and switch to Mobil-1* I rate Mobil-1, very little consumption (compared to Shell Helix Ultra + whatever Toyota used) and it boasts good protection.
