Red Line 42904 V-Twin Primary Case Oil, for use with UTVs, ATVs and Sportbikes - 1 Quart

Great stuff I always use Red Line products in my 08 Dyna lowrider.

Great product that I've used for years

Its red. Its liquid. Its slippery. Bike is happy.

This is by far the best primary oil I’ve used in my Harley. I’ve owned a few and have used redline for years.

Redline all the time grate product only thing I run in both my bikes

Red Line has been a trusted source of oils for many years. I have used it in all of my Harley Davidson touring bikes for decades. I change my fluids regularly and have never had an engine wear issue while using Red Line full synthetic. I highly recommend Red Line for V-Twin motorcycles.

I ordered the case first, it said it had everything WRONG! Harley Davidson is 38 oz not 1 quart. After changing all three fluids I noticed it wasn't enough primary oil. I had to order another quart for just 3 oz I had to wait another week until it finally came. Because Usps said they tried delivering it on Saturday and lied like usual. Saying they couldn't get up my driveway, which I don't have. So far Redline works great thanks. Remember 38oz

This is some great oil, I use it in every thing on my bike. It was shipped very fast and packaged great. I have had no problems with this seller and will buy from again.

For 2011 FLHRC. Has made neutral easier to find.

Great oil for v twins highly recommend .

Best oil for Harley

Performed an oil change prior to a 4600 km road trip. This bike was new to me and therefore wanted my first trip with new oil. Went through some extreme temperatures on the trip and no issues to report. Good products.

Been using it in harley. Change it every coule years. Vety good product
