1992 Oldsmobile Toronado 6 cyl Front Wheel Drive Automatic 116, 00 miles
1992 Olds Toronado Trofeo, 3.8l with 116,000 miles. Am experiencing fluctuating to high oil pressure. At idle getting a good pressure around 38psi. At highway speed/RPM the oil pressure will fluctuate between the low 60's to mid 90's sometimes even into the hundreds. No reason for the fluctuating as the RPM's are pretty much constant but will be in the 60's for a few miles then up to the 90's for a few miles and everything in between.
Car is only driven in the summer and had the same problem last year where pressure readings were in the 200's. Replaced the oil pressure sending unit when I did my oil change for winter storage and this year it is better but still fluctuating more than I would like.
have the same problem?
