Recommended motor oil

Do not use synthetics, these are too thin.

I wasn't aware that synthetics used a different viscosity scale than conventual motor oil.

Marty,

 

Greg over at Bimmers R Us, whose experience with 02's goes back to the 80's, had helped me with the Kugelfisher installation and setting advised to stay away from synthetics as they were too thin.

AFAIK 20w-50 synthetic is the same viscosity as 20w-50 conventional oil (or a 20w-50 "blend" for that matter).  Viscosity is set by SAE standards, for an oil to have a specified rating, it must meet the SAE criteria.  Of course every oil company has its own additive package, the contents of which may make that brand more desirable for our cars.  And flow rates may differ slightly due to synthetic being more "slippery." But to say a synthetic 20W-50 oil is "thinner" than a conventional 20W-50 flies in the face of those SAE standards.  At least that's what I've been reading for as long as synthetics have been around.

PS--unless you're driving in very cold conditions, the preferred oil weight for M10s seem to be 20W-50.  Your choice of brands...

Some education on why synthetic oil is better than dino.  Suggest watching episode 3 on laboratory testing also.

 

A radiator shop is a good place to take a leak.

 

I have no idea what I'm doing but I know I'm really good at it.

LOL....it has been a while since there was a "what is the best oil" thread.

 

and the answer is, like every other time this comes up, there isn't one.  everyone has anecdotal experiences which point to the one they use....and they are all different.

 

the manual calls for specific grades and viscosities for different usages.    use that.   does not matter dino or synth.  or what brand.   just change it regularly and it will all be fine.

Yeah, what kind of “additives” they puttin in there?

You should ask that of any supplier if you are concerned about Amsoil.  You won't get an answer from anyone.

I like to buy this kit from FCP, used it in my E30 and my 2002 and have gotten good Zinc tests from Blackstone Labs. Comes with everything you need and I like the Liqui Moly product, it has never let me down!

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
