I'm with Groper Shell V-Power is rubbish put it in my wrx power brumby and almost lost her the XR6T almost the same. Also had problem with V-Power in the old boy stock XR8. Put BP bak in all of them and never have a problem since. You thrash them on hot or cool days with Bp and they love it on V-power is scare with so much money invested in there engines. Well that's my 2 cents
