Owner reviews for engine oil

Rotella 5w-40, for no other reason than it is good oil that I can use in every internal combustion engine I own, including wet clutches.

Mobil1 V-Twin 20W-50 in all three holes.

My 2014 had 226K changed it at toyota every 10K no issues

I've used for the last 20k miles and no problems! Just change at 5k.

I’ve been using redline in my 2020 fxlrs for the last 3 years. A few guys I know swear by it.

I use Amsoil, all 3 holes.

The Engine oil is proven, the claim about the gearbox oil helping to find neutral easier was true for me, and the primary fluid does just that.

So far redline 20w60 is doing great in the summer heat

My first service after purchasing my Harley, I used SYN3 in all three, since then I’ve religiously used REDLINE kits.

Wife has a 2015 jetta with the 1.8t and burns 1L every 500 -700 miles. My 2016 a3 burns relatively nothing but maybe half a liter every oil change interval and has same engine.

Engine was noisier with the mix vs. the previously used redline 5w40. Iron levels are up at 6.3 ppm/1000 miles Oil usage increased by 1/2 quart over the redline 5w40 TBN/TAN levels are worse than 5w40 at comparable mileage
