we use this on the chrysler crossfire, and other similar cars. the thickness is like water. i wouldn’t recommend using it on motors designed for 10w30 or even 5w20. it is too thin. as for cost, i think we charge around $15 per litre. ---

best oil grade in QR25’s is 10-40 for a good street oil even weekend track. Race guys use Rottela high grades
