My situation is, I have a full 5 gallon bucket of Traveler (TSC) 15w40 conventional oil (SN). I have a 1998 Mustang with the 3.8 engine with only 79000 miles on it. Ford calls for 10w30 in it, but I am wondering if I could use the 15w40 in it? The thing is, this car sits in my attached garage, and basically doesn't get driven in the winter. It will probably never get started if the temp is below 50 degrees F.
IF you think that would be a little to thick for it, would it be ok to mix it with some 5 or 10 30 that is a different brand??
If neither is a good idea, I will save it to use in my 65 mustang 6 cylinder or my lawn mowers I guess.
