Vp Racing M2 Upper Lube Additive

[Vevapower]

You only need it use it if the car sits for more then 2 weeks at a time...this came from VP race fuels directly....

Although they'd never put this in writing as they'd not sell as much would they.

Mine's been running ethanol for 3 years straight never had an upper lube treatment but it's driven everyday.

So unless you just want some trippy exhaust smells give it a miss... (unless race car)...
