I run Redline Performance 5w-30 Euro in my tuned Kona 1.6T AWD. ACEA C3 HTHS 3.7 (Ester based, not the gutless group 3 Professional series)
It has a very low NOACK of 6 and 1650 PPM of calcium which is low for LSPI and being a Group 5 oil. Also VERY low Ash .06 vs all Amsoil oils are 2.2 Ash, which is very high. Then there is the plus of being Ester based, it has polarity to metals, which I like for todays short piston skirts/dryer startups. Not a big deal, but just an added benefit. I dump at 3,500 miles.
