Reviews of RED LINE parts For Business

I use Redline, similar quality and price to Amsoil, without the MLM BS.

I recently replaced my front and rear differential oil with Redline 75W85 full synthetic.

I've used Redline 75w85 which has the Toyota spec listed on the bottle. Have also used ENEOS 75w90 without any issues.

Under hard driving conditions per the manual reduction gear oil should be changed not just inspected. Almost all off us fall under hard driving. Search around some people have gotten better range out of higher quality gear oil redline I think.

In my experience of trying many different oils, what I think are the best, as far as the engine running cool and smooth shifting are: 1. Redline 15w50

Red Line Racing Two Stroke is the best oil I've run. It leaves a good film and smells the nicest.

It's hard to find GL4 gear oil anymore. The only real GL4 available in the States seems to be Redline. GL5 oils are generally harsher on brass synchros. I've been using Redline since 2007, when I bought my GTI, and it shifts just as well as it did back then.

Redline SI-1 is highly regarded for its high PEA content for carbon cleaning.

I just put Redline 5w-30 into my 2011 STI at the last oil change. We'll see how it goes.

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
