Regular fuel add BG 44k fuel cleaner Everytime I change the oil

Whatever oil you do use add BG EPC to it will keep your oil from oxidizing and breaking down longer.   I don't run high octane fuel instead every oil change I also add BG 44k to full tank of fuel - cleans whole fuel system w out doing a fuel service and coats the system to keep fuel related deposits from forming which is what will cause the mechanical failures. Need to find a dealer around you the uses the product check auto dealerships if you can't find one near you and ask them for it.

Find a dealer that has BG products look for three part kit EPR,EPC,44k. Auto dealerships will likely have it somewhere near you and can buy kit from them.
EPR will clean sticking rings restore compression etc.
EPC with new oil (additive)
44k best fuel cleaner you can find.

Good luck!
