---------------------------------------------------------------------- Date: Thu, 30 Sep 2004 22:06:00 -0700 From: "Scott & Charlotte Miller" <[EMAIL PROTECTED]> To: "UUC Digest" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Subject: Re: <E36> diff oil Message-ID: <[EMAIL PROTECTED]> Brian, I attended a tech session presented by the president of Red Line Lubricants. Sadly, I cannot remember his name, but he is also their head chemist. I asked him the same question. The 75W-90 contains friction modifier and makes the limited slip clutches lock up smoothly and noiselessly. The 75W-90NS contains no friction modifier, and is intended for open diffs. Folks who use their car for competition will sometimes put the NS in their limited slip diffs because it allows the limited slip clutches to lock up faster. But, it makes the diff really noisy going around turns. Mr. Red Line told us that new limited slip diffs need more friction modifier than ones that have been completely broken in. The 75W-90 is designed for new limited slip diffs. A common practice is to put a 50/50 mix in an LSD. It provides sufficient friction modifier to quiet the clutches, but still lets the clutches lock up faster than with straight 75W-90. I've been running the 50/50 mix for about a year, and I'm happy with the results.

How about this scenario instead: You put your clean oil pan under the car, drain the oil into it, go up top and change the filter, and then add 6 quarts of fresh oil to the engine. Then you have another beer, and go under the car to button up the drain before adding fresh oil. You are shocked to find twice the amount of oil in the drain pan! I'm just trying to find an explanation that doesn't involve running the motor with twice the normal amount of oil in it. :) -- "It is an honor to be Cookie Monster." -Sesame Street spokeswoman Audrey Shapiro ------------------------------ Date: Fri, 1 Oct 2004 11:22:26 -0700 (PDT) From: "Neil N." <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Re: How much is too much (oil)??? Message-ID: <[EMAIL PROTECTED]> John, I don't drink. Besides, under that scenario, I would have 12 quarts in the drain pan, and 0 in the motor. Which, considering I ran about 125 miles on the track yesterday, would be quite impressive. The one immutable fact of this whole thing is this - I ran that car on track with 11+ quarts of oil (net of LubroMoly). The mystery continues... --- John Bolhuis <[EMAIL PROTECTED]> wrote: > > That sounds improbable to me.

Message-ID: <[EMAIL PROTECTED]> Anyone found a decent vacuum hose diagram for the M50 motor? I can't find one in the Bentley shop manual. My goal is to change as many of the vacuum hoses as possible without having to do anything extreme (such as remove the motor or any manifolds).

The sounds is accompanied by a vibration through the wheel. I also get this occasionally with normal driving, especially in the morning after just starting out. It doesn't look like its hard to remove the power pump and the other day, on bimmerparts.com, I noticed that a rebuild kit seems to be about $25 or so. Any chance that a simple rebuild could successfully remedy this, or is it also possible that the cause is not the pump, but actually a tie-rod-end ball joint or something like that???

So I've got an OZ DIY-WB kit (air/fuel ratio) that I built and used with my old RX7 ITS car, but now I want to use it on my 1993 325i WITHOUT removing the stock O2 sensor - the voltages are NOT compatible. Has anyone installed a second O2 sensor hole upstream of the cat and stock sensor location? A local shop says it could take 1 to 2 hours of work, but looking at the pics, this seems like it should be easy to drill a hole and weld on the fitting in about 30 minutes max. Any advice as to how much it should cost to do this? AND, if you live around Indy and know a good exhaust/weld shop that might do it, lemme know.

Dividing by zero would be bad, but while standing still it's miles that is zero, not gallons. Now my bicycle computer has an option not to determine avg spd while I'm stopped, but that's different. BTW - every car I've ever driven that has a avg mpg reading in does what you're seeing. Especially if it's just reset prior to coming to a stop. I've never played with that feature on an E30, but it counts down on my old E36 and on the E39 when stopped.

We're talking average mpg over time of engine operation, aren't we? Not mpg/mile (odometer) or mpg/mph (speedometer)? If I leave my car idling in the driveway until it burns a gallon of gas, I'm getting 0 mpg. I went zero miles and burned a gallon of gas. (If I were metric, I'd be averaging infinity liters/kilometer.) On my E36 325is with the full OBC (my M3 just has temp/check control), resetting the avg mpg at cruising speed could get me an indicated avg around 28 mpg. If I soon slowed to a stop, the number would count down rapidly. After driving awhile, the time of the average would extend, and the avg mpg reading was less sensitive.
