What should oil pressure be on 98 SL500?
Hi there,
I was at the dealer today and test-drove a 1998 SL500 with 83500 miles on it. I could not open black plastic oil filler cap. Is there a trick to it? Seemed to have whitish corrosion on metal to the left and right of the plastic cover over the engine, is that normal? Car started fine with some higher pitched noise for the first minute or so. Dealer said vacuum pump. Does that sound right? Car had a longer brake pedal travel than my 420 SEL. Like an inch before braking started and overall softer feel. Is that normal or would fluid change and bleeding take care of that? Drove fine, but once warmed, I noticed relatively low oil pressure. My 420 with 60,000 miles has 2.5 oil pressure at 500 rpm, this one was closer to 1 and even at 1000 rpm it wasn't at 2, where my car would be already at 3 again. Is this normal??? AC worked, but I have not operated soft top, as HT was on. Dealer wants 17,495 for it, incl. hardtop. Any thoughts, please Thank you

Oil caps get stuck - new cap or new gasket would help. Air pump noise on cold start up is normal. Oil pressure sounds OK, consistent with owner's manual. That's the last year of the 119 motor - desirable in my view.

Thanks, guys,
I am surprised that the oil pressure is so low as per manual, particularly as it compares to my 420, which is a V8 too, just a bit smaller and 11 years older.

Hi again,
I found a picture on the internet of the SL instrumentation. This to me looks like a good oil pressure, with temp. may be not quite at operating, but close, rpm at 600 and pressure at 3. The car I looked at showed a lot less. Would you agree or can you "doctor" this picture? Thanks again

Not natural that it would be at 3 at idle - could have just been reved. There wouldn't be any point of having a gauge if it always read 3. Owner's manual gets it right.
