Mixing different brands of oil.

It shouldn't cause any problems at all. It's a good idea to stick to the same viscosity though.

Thank you James for the prompt response, and for it being the one I was hoping for........ Since the wagon is using quite a bit of oil, and the price of oil has risen so high, I grab any of the brands mentioned that are on sale.

CHEAP OIL AIN'T CHEAP the seals leaking might be an issue so they will need replacing even if they are ok better while it's easy to access to replace the seals as well . Junk oil is junk oil ,cheap oil is the best you can afford .
