This coats the asperities in antiwear additives and friction modifiying additives that will allow the asperities to bend over and slide past each other. The reason this is better is far less small chunks of metal will be generated, small chunks of metal cause huge amounts of wear. 1 Link to comment Share on other sites More sharing options...

If the dealership , were they also relucant to change the oil and filter as mine appear to be ? Is there a warranty issue - if we do not follow their recommendation ?

I haven't asked if this would void my warranty and don't see how it could. I doubt they could even tell. I use factory Ford parts and the recommended Castrol 5w20 oil. I wouldn't suggest changing the oil weight in any car away from what the car is has been designed for. The lubrication engineers at Ford know a lot more about oils than most mechanics and forum members. Certainly changing oil from a mineral oil to a full synthetic oil too early can affect the bedding in of the rings etc. Benny.

Agree with Rapid , it's cheaper to replace oil than a motor 1 Link to comment Share on other sites More sharing options...
Rapidyellowxr6tute Donating Members 123 Member For: 13y 1m 5d Gender: Male Location: Yarra Valley, Victoria Posted 30/01/13 09:07 AM Share Posted 30/01/13 09:07 AM OK, for those still interested in this thread I have done alot of ground work and found out from Ford directly that the Miami 315 & 335 engines do 100% come of the assembly line with the recommended 5W-20 Castrol Edge oil so there is no such thing as a special run in oil with these engines. Also, you can change your oil and filter whenever you choose to without any problems with your warranty as long as a genuine filter and the recommended oil is used. The reason Ford don't recommend or like doing this is to do with cost issues apparently (from the horses mouth) which is why the majority of service managers at dealerships will look at you a bit strange! I have also found that unless you purchase your oil direct from Ford it is only available in 20 or 60ltr drums with the 20ltr coming in at just under $360 so it certainley isn't cheap stuff and a 20ltr drum is only good for 2 changes as the engine holds 8.5ltrs. So for all of us wanting to do in between oil changes, it will have no effect on your warranty so if you want to dump the oil at 1000ks or 3000ks.....go for it. The oil can be a litle difficult to get as it was a joint colaboration between Ford & Castrol to develop it so they like to keep you going back to them for your services but you can get it.I hope this helps some of you guys with your concerns regarding this subject.Cheers, Rapid 5 Link to comment Share on other sites More sharing options...

A fair bit cheaper too Link to comment Share on other sites More sharing options...
