Frequently Asked Questions

Can I overfill the engine at an oil change?

The E07A holds only a few quarts, so fill to the dipstick and no higher - these small engines do not like running overfull.

How often should I change this filter?

Change it with every oil change. On a hard-worked Kei truck many owners run a 3,000 to 5,000 mile interval; match it to how you use the truck.

How do I know when this oil filter is due?

You cannot test a filter directly, so go by the oil change. If the oil on the dipstick is dark and gritty, or the filter has been on for more than one change, fit a fresh one with the oil.
