Mobile 1 MX4T 20-50 synthetic
Avaiable at autozone

 

hey tundraotto.. You say the Fram uses cardboard for it's bypass valve. What is this and how does it work. I didn't know oil filters were this complicated . What are the bypass valves normally made of.

What about these oil filters are they bought at the stealership or can you also get them with the oil at autozone? what's the # ?

 

I have ran everything in my Raptor.
Maxima 15w-50, Valvoline Synthetic, Quaker State Semi and full synthetics, Mobil 1, Pennzoil....you name it. I currently have Quaker State Semi-Synthetic 10w-30 Truck oil in my Raptor....which is a little thin for the warmer weather.

 

i use yamaha filter and yamalube so far. I might try that AtV engine oil i think valvoline makes. One thing i always try to do it go with the thicker oil for better protection. One thing u gotta remember, if you go on the thicker side, always warm up that engine or your really gonna strain things. Good luck
Right now im using 10-40 and it workin great. In the summer ill prob go to 20-50. In the manual it tell you what viscosity oil to use at what temperatures.

Give it a look. good luck and happy riding , warrior

 

I running valvoline as well, its car oil but not with the energy conserving additives and it exceeds all of the grades in my service manual. 10W30

 

I always use Torco 10-40..no probs.

Bosch 3300 or STP 6607; both at Autozone.

 

I use amsoil 0w40 4 cycle synthetic motoroil along with a amsoil superduty oil filter #smf103.

hope that helps
