Your best bet is to use a thinner weight oil
it is in your owners manual
here is the manual if you do not have it
located on page 55 is the wiring diagram where you can find the oil pressure switch
Yes... The manual showed a thinner oil for these temps but I was concerned about synthetic... Local dealer said OK as long as SJ even though the manual did not address synthetics...
So I put in synthetic SJ type 5W30 and it is working perfectly again!
Not sure why all of a sudden the use of 10W30 regular oil started this problem... Worked fine for two seasons at Deer Camp before! Cold nights back then too!
