Today I stopped at Wal-Mart to get a gallon of antifreeze for the MH and car and as I passed the motor oils I saw that they now carry Mobil 1 blend in
15w-50 full synthetic. So I got a 5-quart bottle.
I was going to use Shell's Rotella T6 in 5w-40. Polaris says to use there 5w-50. For most of us, there is no need for 5w because we do not use the ATVs in the extremely cold weather for the easer starts; that is more for those in the sub-zero temp. But yet I do feel the 50 is good for the heat that these machines put off. We do not get good air circulation of air around the inclosed engines.
The biggest thing that caught my eye is that Mobil 1 is for use in car engines and not DIESEL ENGINES as a
heavy duty motor oil.
The Mobil-1 comes in a 5-quart container priced at $25.47. Which is 1/3 the cost of the Polaris oil.
I do not use the Polaris filter; I have been using the HIFlo oil filters.
"HF199".The box is marked replaces Polaris 2520799; which is used on my 2018 850 SP. For those that have not heard of HIFO filters, they are known for making original equipment filters for many of the high-end autos. I have been using their filters on my ATVs for over 25 years; and have no problems. You can find them on E-bay and at some bike wholesale parts stores.
