FiveOhB: I have been hearing different opinions about if the dealer will warrant our warranty if we change to a different velcosity oil then the recommended 5w20. Some people say (and hubby) that it won't hurt the warranty if they find out that you are using the 5w30 and some people say that it will void the warranty.

What do you say about the matter?

I just change to 10W40 Valvoline Durablend for this oil change. Next change will be full Valvoline synthetic. I'll run the 10W40 in the winter and 20W50 in the hot Houston summers and on the race track.

I just had my oil changed at the dealer and they put in 5W30. I questioned it but they were not concerned. I questioned the warranty issue, they said don't worry. I pushed some more about the manual specifying 5W20. Their final answer was that they made a mistake on the bill and they really put in 5W20. I doubt it....

The oil weight is not that big of a deal but if the oil meets the new

Ford Specs WSS-M2C153-H


is what you need to look for. I have only seen one oil, Superflow by Exxon, in the parts store that advertised on the label that it meets the new Ford Specs WSS-M2C153-H. NOW that is not to say that some of the other brands do not already meet it, but Ford and Honda spent 3 years getting this specification to market. I am sure we will see more and more of our favorite oil manufactures advertise that they meet the new spec as time goes on.

More 5W-20 concerns....

Checking some of the major oil websites I put the following information together.

I was suprised at what I found at the Shell site and that is GF-3 is not the same as the Ford
WSS-M2C153-H.... They list their 5W-20, 5W-30 and 10W-30 meet GF-3 but ONLY the 5W-20 meets the Ford WSS-M2C153-H. I may be mistaken but I was thinking that the new WSS-M2C153-H was to become the new GF-3 requirement.

Maybe the Ford WSS-M2C153-H is the GF-3 with oil weight of 5W-20...

If this is true then this may be a big concern down the road.




Below is a list of the sites I looked at and if they even referenced GF-3 or the new Ford WSS-M2C153-H
