Maxima Racing Oils CS30-069128-4PK 20W-50 V-Twin Mineral Engine Oil - 4 Gallon (Pack of 4) - Premium Motorcycle Oil for Harley-Davidson, Indian & Cruiser Bikes - Ideal for High-Performance Engines & Long Rides

I purchased this oil for my Harley Davidson. I run 20w/50 most of the year and the 15w/60 in the summer. Being a Harley Davidson The bike gets hot when doing the occasional mono. This oil seems to withstand the abuse the air cooled engine gives it. As it should!… Stay safe on two wheels and the occasional mono.The weather is too cold too ride here in the Northeast. Lol but as soon as it warms up I'll put the oil in I'm sure it's great stuff used this brand before in motorcycle. I used this oil this riding season great oil. Mineral oil withstands heat alot better than conventional oil does. 85-90°f and still had power and performance. I installed a oil cooler on my Harley and can tell the difference in performance runs good usually doesn't go above 204°f. I way I ride though this oil usually last for 3 months than it gets black and I dump it, great performance for the price!!SweetOnly brand I use in my harley.I started using this engine oil in 2019 and haven’t been back to the Harley dealer yet! I’ve heard great things about this oil from several other people that have been using it for a long time. This is the third time I’ve ordered it from this seller and every time I’ve received my order and less than 48 hours! Great price, great product and great customer service.Awesome price for the amount you get.Works fine in my 1200 Sportster. The motor is not as loud as with synthetic oil.This is good oil for my Harley and a great value for my money. I will buy again.Excellent
