Castrol Classic Valvemaster Plus with Etha Guard Fuel Additive Original 1770

I'll report on this in a tear or so!

It arrived several weeks ago. As anyone with any nous knows you cannot evaluate additives in a trice.

It will take months. Fingers crossed it will work!

Perfect for older vehicles

Perfect for use on a classic motorcycle which used to require leaded fuel .
Also removes the need for e5 petrol and can be used with e10 safely.

You ask for reviews too soon.

Too soon to review properly as only filled tank once. Seems ok.

Good for old bikes.

Still to try this product but been pleased with previous Castrol additives. Surprised it doesn't mention Octane boost.
