hey guys I posted something about this before but now after doing an oil change nothing has changed. I originally thought maybe it had something to do with the Mobile One oil filter. I did my oil using regular Delco filter and the usual Mobile One 5W30 Synthetic. Well I still have my problem. At WOT really noticeable in 1st and 2nd there will be a brief fluctuation in my oil pressure gauge from the normal reading down to a little below 40 and then it will go back to where it should. Can it be maybe my oil pressure sending unit going bad? Car has 60,000 miles, never any engine work done except basic bolt ons, and always maintained very well. Any ideas would be greatly appreciated.
Thanks
