We have a lot of synthetic 10w30 oil left from the previous car. Can I use it for our new 1219 Foresters?
Another old time saying is seeing someone step over dollars to pick up dimes.Call me crazy but how much oil could you possibly have that is worth not following manufacturers requirement. I’ll guess it’s less than $100 if that.
It’s your money and your $30k+ car so you get to make the call.
Not gonna happen. Magnuson-Moss Warranty Act states among other things that the vehicle defect has to be the result of customer abuse. And Subaru must PROVE that it resulted in damage.Not unless you want to potentially void your engine warranty.
