I believe at one point those Mazda 2.3L engines were spec'd for 5w30, then later back spec'd to 5w-20 probably to get the fuel economy numbers up just that hair higher, Mobil1 0w40 is pretty starts as a very light 40 and shears back to a thick 30 for most of the OCI, go right ahead and use it.have M1 0/40 for the MB can I use it in ford fusion 2.3 with 108 thousand miles, that calls for 5/20
MI 0w-40 is one of the better oils on the market.Why would you want to do this?
That's a pretty broad statement.MI 0w-40 is one of the better oils on the market.
AgreedThat's a pretty broad statement.
A 0w40 will be thicker than a 5w20 at winter temps?Agreed, use with confidence. I tend to keep the heavier oils (40 & 50 weights) for the hot summer months, but running it in winter isn't going to really harm anything, it'll just be thicker at cold start temperatures (not ideal in winter) than the 5w-20 you've been using.
