jimmys Posted September 17, 2007 Share Posted September 17, 2007 Hi When I cruise at over 70mph the oil light on dash comes on. I have to slow down then it will go away. If I drive at 70 or less then it won't come on. I have changed oil sender sensor near oil filter but no fix. Any suggestions. thanks Quote Link to comment Share on other sites More sharing options...
jeffls400 Posted September 17, 2007 Share Posted September 17, 2007 If you are referring to the oil level light (amber) and not the oil pressure light (red), I had a similar problem when cruising at high speed. The oil on the dipstick was just below 1/2 way between the two marks so I added a little bit of fresh oil and have not seen the light since. The sender that is mounted near the filter is the oil pressure switch. The sender for the oil level sensor is on the other side of the engine. Hope this helps.

SKperformance Posted September 18, 2007 Share Posted September 18, 2007 Is it low oil or low oil pressure? I suppose you have the proper amount of oil? Quote Link to comment Share on other sites More sharing options...

cardona6569 Posted September 20, 2007 Share Posted September 20, 2007 You should check the oil pressure with a manual gauge. I suspect a bad oil sending unit. If it were your oil pump, you would have no engine by this time. An oil starved engine would seize quickly. CPR Quote Link to comment Share on other sites More sharing options...

ROYT Posted September 20, 2007 Share Posted September 20, 2007 How many miles has the car done? 5/30 oil is hot and thin at high speed, you may be better with a thicker grade..... Quote Link to comment Share on other sites More sharing options...
SKperformance Posted September 21, 2007 Share Posted September 21, 2007 Sea foam it as the sensor may be varnished. Quote Link to comment Share on other sites More sharing options...

ROYT Posted September 29, 2007 Share Posted September 29, 2007 You could try 10/40 for a start and see if thats better. Don't know about Seafoam...don't think this is available in th UK cheers Quote Link to comment Share on other sites More sharing options...
