Red Line 20W 60 Oil Shovelhead HD
I had the oil pump on my 1981 HD shovelhead fail.I rode approximately 100 miles and the engine miraculously held together. I swear by this product for old Harley's. It is expensive, but then, so is an engine rebuild.

PROS: Oil pump was broken, Stays on cylinder surface, Handles extreme heat, Worked without pressure, Handles wide gaps, Kept engine from blowing

CONS: Is expensive, Is hard to clean up

Redline makes a great product
I've been using it in my 98 Dyna Wide Glide for a few years now and it runs great and I'm very happy with it, I put 15,000 mile on it last year and it runs like the day I bought it.

PROS: My Harley Loves Its

Awesome Oil!!!!
I was using the manufacturers synthetic oil because that is what my maintenance program I bought would mostly cover after initial bike break in. I did some research with the various synthetic bike oils out there so I could make a change since I have been changing my own oil for a couple of years now. I wanted something better basically. A friend and co-worker of mine said he used Red Line Oil in his bike and has driven from Texas to Montana and back without any issues. So I decided to try Red Line Oil and what a difference it makes!!! It goes into gear and into neutral better than ever. Smooth shifting, a bit more pep and a bit better gas mileage since putting Red Line Oil in my bike. Best decision I have made in a long time. Thanks to Cycle Gear and a big Texas thanks to Red Line Oil.

PROS: Better Gas Mileage, Improved Hp, Smoother Gear Engagement

CONS: None that I can think of

Top of the line
If you ride an air cooled 500cc single on the street as I do, or just want the best syn motor oil for your ride, Redline oil is the one to get. I bought my bike with 1800 miles on it. It has 8700 now. I change oil with Redline syn every 2500 mi. The motor dosen't smoke or use oil and it seems to run cooler.

Top shelf oil
Redline oil is pretty much the highest quality motor oil you can buy. Base stocks appear to be higher quality than other brands.

PROS: Lubricity, Heat resistance, Longer Drain Interval

CONS: Cost

BEST USES: High Performance Engines, High Sustained Temps

Redline Motorcycle Oil Purchase
I have ordered redline 20/50 motorcycle oil online from cycle gear before,the process is easy and I get the product within 5 days. Wish the online order per qt. could be a little cheaper than actually purchasing it at my local Cycal Gear though(only reason I give it 4/5 stars).Overall a good transaction,no problems.

PROS: Quickly Received Purchase

CONS: Online Prices Are Same
