Has anybody used ZX1 extralube in there wrx? If so would they recommend it?

 

I don't know. You ask a simple question..........

 

What is it? If it's an oil additive, they're generally not well thought of in Drivetrain ...

 

It reduces drag and it aids in reducing friction. It's mean't to be good for cold start ups as well. 90% goes in with oil and the other 10% goes into the fuel tank. 225 ml bottle. £17 from halfords. gives alot of good information in the instructions.

 

friction reducers = bollox

save your money and use a good quality oil and filter

 

You'll get mixed answers from everyone. I've used it on me motor, coolant, fuel, power steering and gearbox/diff. Nothing noticed from engine etc but gearbox feels more smooth and doesn't klunk the gears like it used to.

As friction reducers go, it's the best...mix with anything, anywhere, but not sure if it really works since the oils I use are excellent quality anyway.
