Ihad my honda civic in the shop for an oil change last thursday. Saturday morning, my son told me it's leaking on the garage floor. Took it back to Pep Boys and asked them to look at it. They thought it was leaking where the filter goes in so they took the new filter from Thursday out and put another (same brand) in. Sunday morning...still have a leak. Back to Pep Boys, get a totally new totally different brand of filter...this morning...STILL leaking. Any ideas?
