Snake oil...................... Go with straight 40 weight and keep running it ! I do it with my ancient "winter rats". My 87 Escort never complains...LOL! |

ran with the motor burning oil at about a quart to every 250-300 miles IIRC. As a goofy young lad of 18 I failed to keep it topped off constantly and one day running down the Mukilteo Speedway north of Seattle it just...ummm...sputtered and froze up. Yep, I kept it alive and had a rebuilt 6 cyl 200 c.i. engine thrown in the nice looking Stang. The next major failure was the transmission and the car was gone, making way for a 1970 Chevrolet Suburban. Ya wanna talk about beasts to drive. Probably achieved 8 miles to the gallon in that people mover!

and was willing to trade a '65 Mustang with a borken tranny for a good running rig. It was between a '73 AMC Gremlin and a 1970 Chevrolet Suburban and I chose the Suburban. The sub-10mpg forced another choice, though, within a few more months. Sometimes wish I would've chose the Gremlin but it seemed a little small for us. Ended up with a '66 Ford Fairlane I quickly dubbed old Smokey. |

Replying to: Mr_Shiftright (Jul 02, 2005 4:14 pm) I have taken the car to the dealership on multiple occasion. There is no leaking, the underside is dry as a bone. There is no discernable smoke on start-up or in motion. Power and gas mileage is great. The compression is within norms. The dealer conducted some form of test and removed / replace valve in the crankcase - they said it was out of spec and sucking up to much oil. This did not solve the problem. The dealership now has me using 10-60 M3 High Performance Motor Oil. They are trying to go the cheap route and not teardown the Engine. I think I have a problem within the Engine -i.e. rings , valve guides, etc. If what i believe is right - what can be fixed first without too much fuss and money, Or should I just have them tear the Engine down and put in new valve guides, rings, etc. The car runs great otherwise - it's very annoying to put oil in the car every 1000 miles. If it was every 3000-5000 miles then I would have no problems, but this is a BMW - it's supposedly engineered to go 300K - having this happen at 117K is bothersome to say the least. Looking forward to your help. Regards Manny Mateus

Sure, you could have someone tear down that engine, hone the cylinders, put in new rings etc. You could easilly spend 4000.00 and turn your 1000 mile per quart BMW into a 3000 mile per quart oil burner. Do you really think it's worth the expense? For me, simply adding a quart of 1.50 oil once a month isn't a big deal. And I don't like their reccomendation of using a heavyweight oil to mask the problem. 10-60?? Never heard of the stuff? |

And why would 10W-60 oil significantly slow the burning? The designator indicates the basic oil is 10 weight, and has elastomers added to cause it to simulate 60 weight during full high temperature running. To top it off, I've read that some manufacturers consider 1 quart per 1000 miles to be acceptable oil consumption.

All cars use SOME oil. They have to. To me, 1000 miles isn't a big deal at all. Just check it often to make sure it doesn't get worse. I remember I once had a Chevy that used a quart every 700-1000 miles like clockwork. I kept that Chevy five years and it never changed. Ran like a top too!
