Validity of new Oil Temp Gauge?

Oil temp mostly determined by ambient temp and road speed. In a stock Type 1 running 70 MPH at 90F outside, oil can easily go to 200F.

There's no "magic" number and with today's multi-grade oils lubrication failures from too high temp are certainly rare in the VW engine. By far the greatest number of engine failures are from exhaust valve/seat failure.

Find out from experience what temps to expect on *your* engine relative to speed and ambient and use that as a guide to warning of cooling system problems.

yep...i have a beautiful example of a perfectly good running, nice consistant head and oil temp engine with a broken #2 exhaust valve...without notice(no excessive valve lash at adjustments) it went.... JT

Sounds normal to me. You get the higher oil temps doing highway cruising. Bugs love stop-and-go and cool down pretty quick. Absolute max temp I consider 260, with 240 being my yellow range.

I agree with Jim, abnormal for you is really a comparison to itself.

But here's a comparison to me. My old engine with a hammered main bearing, some go-fast goodies and NO external oil cooler would hit 260 in about 45 minutes of level highway cruising and could only do 20 psi of oil pressure @ 3500 rpm (about 65MPH). It was a shot engine and not healthy.

sounds about right... i had a stock 1600c in my 72 beetle with a VDO oil temp ga. with a drain plate sending unit and it would run about 190-205* that was in so. florida in the summer time about 95-98* outside with 80-90% humidity

Ok, just gave it a better test, so PLEASE tell me what you think of these numbers:

Temp gauge at highest point reached just-at-220*. When I arrived in town and drove the 3 miles from the highway to home, it dropped to +- 200*.

Would *this* be considered "normal" for most motors, and secondly, where is the "shut the darn thing down now" point?

Thanks, Larry

your temps look good to *me*....i shut down if it hits 250....have only had to shut down ONE time in fifteen years...but that was because the engine was a "mutt" that someone had mixed and matched parts before i bought it... JT

Good temps. Drive and be happy. One good thing about Mobil-1 is that a crisis or two doesn't ruin it. When it gets much hotter out you might check again.

The Puma came with a factory oil temp guage. The factory said hot was over 230 degrees in my manual. My super ran warm all summer over 200 degrees. I like 190 to 225 in summer. I don't have a guage hooked up in the bus yet but I will soon.

I would say yes.

I consider "shut it down now" at 260.
