Engine Oil

I would assume a 2014 is still under warranty? Then I would recommend doing what the owner's manual says and using the products the owner's manual says to use. After any warranty runs out, then experiment with different oils.

Why don't you read your owners' manual? If you don't have one, a dealer would give you all the info you need. Just bring the VIN# to him. Won't even charge you for the info!

It won't hurt your engine to switch over to synthetic oil from regular motor oil! I did it it my coach when it was brand new many years ago. I use Mobil 1 Synthetic 5W-30W with the gold cap on the silver bottle it's extended range motor oil. My coach is very similar to yours you should change oil using Mobil 1 once a year or every 7,500 whatever comes first! Happy Trails

The 5w-20 recommendation must be a carry over from the cars where it is used to maximize the EPA mpg test. I would never use it in an engine that works as hard as a gas engine in a MH. At a minimum, I would recommend a synthetic 5w-30. I use Mobil 1 5w-40 oil in my V10.

The advantages of a good synthetic include not shearing down (a 5w-30 oil becoming a 5w-20 oil) with usage; the ability to handle the higher operating temps common in a MH without breaking down and coking the engine; and the ability to not have to change oil in the middle of a long trip.

Anyone know what kind of oil is put into a 2014 Coachmen Mirada. I do not know if it is regular oil or synthetic. Does it matter if I switch it to regular oil. Is there a place in the coach that says it? I looked in manual and did not see it anywhere. Thanks for the help.

Open hood. little to left of center oil type is on cap. 5w-20. Use Ford oil. My 2012 F53 chassis takes full 8 qts with filter. My F250 PU V10 takes 7 qts. Who knows why.

Page 297 This is the third printing manual on Ford site.

7 qts, 5w20

Look on the oil fill cap also.

I am reading from the OP that this is a 2014 new vehicle. So why would you state to use a high mileage oil in a new warranty engine. Over 60 vehicles come from the factory with pure synthetic as a factory fill and Ford is listed as one of them. The part# list on page 297 converts to full synthetic Ford motor oil.

if it has, I won't go back to reg. oil. need to find out from the motor manufacturer

Use Castrol High Mileage oil, it is part synthetic and part regular oil. It is the best at a descent price. Full synthetic oil is not normally put in by the mfgr. in most vehicles.
