Reviews of RED LINE parts For Business

Redline 10w30 full synthetic if I know I'm going to beat the piss out of it for the next 5k miles (think autocross or mountain runs), otherwise I use Honda 10w30 full synthetic.

I do not use auto oil. Motorcycles run hotter and I don’t trust car oil. I use Red Line. They sell a V-Twin kit that has engine oil primary oil and transmission oil, and fuel system cleaner. I buy one each spring.

Redline 85+ has worked well for me in past on my ALH, they also have diesel fuel catalyst

As far as fuel additives, they're best used to clean injectors and keep them clean. The best for this IMO and the one I use is Redline SI-1, best ingredients the details of which I don't recall of the top of my head, did the research long ago.

Redline 5w30, the best

If you can use Redline 5w30, go right ahead. You will not have an issue. I call Redline the guarantee oil. I can pretty much guarantee that you will never have the dreaded lifter tick. It has been known to quieten a ticking engine too.

It's recommended by Nissan to use ester based oil. I use redline 5w-30. Pricey but I feel the difference and motor runs flawless imo

Using Redline 5w-50 on my E90 M3. it's supposed to have a similar viscosity at high temps as most 60wt oils. Comes up to operating temp faster and doesn't overheat.

Redline Light ShockProof gear oil. Or Heavy Shockproof if you don't mind your gear changes being a bit notchy until the gearbox heats up.

I disagree with any redline product. I've had 3 VW's always used VW gear oil, never a tranny problem. My Scirocco has 160,000 miles and the tranny has never been touched. Whenever I hear of someone haveing major tranny problems needing a rebuild I've always asked if they were using Redline, and the answer is always yes. See, it is much too slippery for VW transmissions. Yeah your gonna clear up your second gear grind and smooth up the shifts but you causing damage to other parts of the tranny like bearings.
