One last question for reconranger, took a look at Maxima oils and I am most definitavely going to swtich over. Just curious what the difference was between their ATV Premium 4T oil and their Maxum4 Premium. I am looking at 10W-40 weights. Both are wet clutch safe, both are made for ATVs both are the same price per 5 gallons jugs, the only difference I see is that Maxum4 Premium says turbo safe. Just curious what is best of these two for my Rancher 420FM.

On the web site, they seem to call everything Maxum4, except the ATV Premium. If you look at the data, ATV Premium and regular Premium have only minor differences. In the old days, the old really ugly weird shaped bottles all said Maxum4 on them. If someone tries to sell you one of those, pass it up becasue it has sat on the shelf for the last 10 years!

I had Valvoline 10w-40 4 stroke atv oil in my recon before I changed the oil today. I put Peak 10w-40 regular motor oil in it because it was much cheaper. Will this change do any harm to my motor.

Most ATV manuals do not specify which motor oil weight to use. They have a temperature graph stating what grade of oil to use in a certain climate. Only Polaris says use this weight oil (0w-40) and nothing else,which is odd to me.
