Superbikes recommends Maxima EXTRA 0w-30 synthetic or Petroleum 5w-30 oil for predator, to help the shifting. Amzoil synthetic is also very good oil rated SJ, and Maxima is only rated SG. Maxima adds friction modifiers, and polaris claims theirs does'nt need it added. plus Amsoil in cheaper. Which one to Use?? Want to help shifting and also want to run the best. thanks for any input.

 

also, has any tried the "engine Ice" coolant in the atv's? they claim to improve cooling up to 50 degrees.

 

I'm sticking with the PS 4 Polaris oil. With the coolant additives, learned from the AZ Boys about using Redlines Water Wetter. The race-mod Sport doesn't need the fan anymore. Stays cool even during 95 degree woods-blasting. Doesn't have anti-freeze capabilities, so what it in the cooler weather.

 

drop some KLOTZ racing techniplate 10w30 in it,you won't regret it...
also if you can to,get some redline water wetter in the coolant at 50/50
best engine protection you ever had....
