Q for those that have oil temp gauges

Yep, I'm in the 190ish range. After extended freeway runs, I get a 200-210 spike for a few minutes when I'm back on surface roads. I don't know if this is normal or not. I think it has to do with the oil-pan sender location vice in the direct stream of circulated oil.

I have trouble building temp. I'm lucky in the summer to see 120 - 150 F. It was so bad - I switched to an 80 C thermostat.

I'm running an Ingraham Improved radiator and Red Line 15w50.

Temperature sensor is on the back of the cylinder head in a VDO dual unit (temp and pressure).

I like to see the oil temperature at 210 Fahrenheit. On cool days, I block off a portion of the radiator to get it to that temp. On hotter days (high 90's - 100+), I've seen 235F... and keep driving (but no drafting). All measured at the oil filter housing, synthetic 10-50 racing oil (in the race car). -KB

the temps are gonna differ a lot depending on where the probe is. i had a vdo probe that went in place of the drain plug in the oil pan, that temp was always cooler. i also had a probe that went on the oil filter head from a tii turbo, which has a thermostatic element that controls when oil is sent to the cooler. at first, i was getting temps of around 220, then it would drop slightly, then go up. i could tell that was when the thermostat was opening, sending oil to the cooler. later on, i replaced the arbeits element to a cooler one, and i would get 180-185, then about 200 with a/c on, and cruising above 65 on the freeway.

10- 15 F higher than water,

without an oil cooler.

Rising to 30- 40 over water at a hot track day...

Right around water WITH a cooler.

I agree with Ken- 200- 210 is a good target.

interesting, I'm also running temp sensor in the back of the head in a VDO dual unit. my temps are always just a bit over 120 F. Radiator = 3-row core similar to Curt Ingram's. Oil = 20/50 Valvoline.

this is exactly what is happening to benneton's car

he's wondering if the motor is running too cool, although it runs well as is

I don't think my car is running cool as water temp guage is at 2:30 position. I'm thinking maybe rear of head isn't getting a good reading since there's 2 of us running in the 120's with the sensor at the back of the head.

Mine was located in the back of the head in a tee in 3 different configurations:

- Oil pressure and oil temp > Very low oil temps, never got over 50 deg celsius.

- Oil temp and turbo oil feed (so continously flowing oil) without an oil cooler > At least 100 deg, and quickly rising to 130+ over 80mph and track use.

- As above, but with a 19 row mocal oil cooler and S14 filter head > Between 80 and 110 deg.

Apparently my oil temp sensor didn't see any fresh oil with the oil pressure sender installed on the same tee.

    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
