thats funny man. 10 gallons p7-r #1 , 15 gallons pc-r #2, 10gallons vspec#1, 15 gallons on vspec#2
thats 50 gallons in a few months, with the weather you have in england i don't think that is possible even if you tried to play all day every day. i smell b.s when i read it
now the truth.... vspec are fast engines, as fast as s7 and p5's and pretty good fuel economy, 8 or so minutes (not the 12 minutes claimed though)
however they do NOT hold compression like RB's do. not to mention some vspecs are a hit and miss affair with their main bearings.
