Red Line 58404 Lightweight Shockproof Gear Oil - 1 Quart Bottle

NOTHING better than this stuff.Quality you would expect from REDLINE..Protect those gears with this stuff.

I have a 2019 Edge ST with 32k miles. Ever since I bought it, it's had a shudder on tight turns that seemed to be coming from the rear diff. I got some of this and drained and filled with it and my shudder noise is gone. The blue color is nice too. Quality product that I would highly recommend.

Brilliant product

I don't leave reviews at all but after using this product, I knew I had to leave a review. Got recommended by my tutor and read reviews about this product before purchasing, but was extremely surprised to confirm that it's legit. I drive a Mazda 3 (2015, BM). My Syncro's are quite worn and was having trouble shifting from 1st to 2nd and recently getting trouble shifting to 3rd, my 2nd gear cluster bearing was also noisy whilst cruising in 2nd, this is with replacing the transmission oil with Mazda's OEM transmission oil. After replacing the oil with this, it's truly a night and day difference. Feels like a new car, shifting is silky smooth and the cluster bearing is not noisy anymore! It does not completely solve the worn Syncro's but it's 200% better than what it was before. Highly recommend and would be buy again.

Unnaturally blue, smooth and slippery though.Hopefully Gargamel sends us a present for slaying all of the local Smurf population while lubing up our undercarriages
