What a Company!

Amazing business to purchase from, I’ve bought gear oil from Performance Improvements before and will continue to do so. Fast shipping every time and product is exactly what was ordered. I had a clunky/grinding NV3550 and the Redline MTL I purchased did just the trick! Thank you P.I. Speedshops!

Very Quick Shipping in Ontario

Ordered Redline Gear Oil for my BMW at a reasonable price. Arrived in one day. Would buy again.

MTL 75W80

Excellent service! I ordered the wrong part, totally my fault. The great P.I. service team, thanks Andy, sorted it out and covered the extra cost. How great is that

a great upgrade for a car requiring light weight gear oil

I bought two jugs of this Red Line oil for my 2014 Mazda3 6MT and i'm very happy with it. I wanted to get rid of the factory fill even though Mazda says it doesn't need to be changed until 200,000km, just to get some quality fluid in there. Finding a GL4 75W80 gear oil was difficult, as very few companies make such a light weight oil, and most are GL5. Luckily Red Line's MTL is 75W80 and GL4 to protect synchros, so it was a perfect match. After changing my oil, I instantly noticed the shifts were a little smoother and more satisfying. That might be attributable to the placebo effect, but at least i know the gearbox is now filled with quality synthetic oil to take care of my gears for the next 200,000 kms.
