We have a skidloader that needs a couple quarts of oil. It has regular 10-30 in it now. We got a case of synthetic 10-30 without knowing it. Is there any reason why we shouldn't add the synthetic? Thanks.
More information might get you a better answer, what brand synthetic oil mixed with what brand multi vis mineral oil ??
