Noticed on yahoo.com/autos that an owner of a cube with 8,700 miles is using a quart of oil every 600-800 miles. I would call this excessive for a new car ! Has anyone in "cubeland" had this issue? :-\ :( :no:

Wow, 8,700 miles, I thought I had alot with 5,000. Sounds like they have major problems. A new car shouldn't be using any oil. also sounds like they should spend more time at home.

I have 5,545 on mine. Two days after I bought it I had syn oil put in. Because I was on the road I had the oil changed (syn) at 4,000.; no problems at all.

The service manager at my dealership said not to change over to synthetic until 20,000 miles has been put on the engine. Synthetic may interfere with the normal seating of the rings to cylinders.

I know that Amsoil says it is alright to put in their oil in your engine right away. If Amsoil (and any other synthetic oil) virtually stops the wear on your engine then how can it not interfere with engine break-in? Breaking in an engine has been described as wearing down the highspots on the cylinder walls until a good seal has been made with the harder rings.

I am going to follow his advice and wait to switch to synthetic oil.

Stops the wear??? I know Amsoil has been around for a wile, but stops engine wear, really?

My Fit came off the lot with a 50/50 blend of synthetic so the user could go either way. I was told once you go synthetic you must stay synthetic and cannot go back to traditional oil. Dont know if its true but my synthetic is guaranteed for 15K miles. Added Syn on the first oil change. Guess we will see.

Yeah, my bet is they have a small leak somewhere.
Last time I had to add a quart at 600 miles is when I got lazy and had Wal Marche' :-[ change oil on my 7.3 F-350. They forgot to tighten the oil filter. :no: Fortunately I had 14 qts still in the pan. I didn't noticed because I was on a road trip. When I came out in the :am from the hotel I noticed my under carriage had a nice coating of rust preventative. :mad: Needless to say they will not be working the Qb. 8)

You can go back to conventional motor oil without problems, most auto parts retail professionals are taught early on to tell the customer it's not good for your engine to switch back just to keep synthetic oil sales up.
