can you put a manual (mechanical) gauge on the engine to verify whether or not the gauge is going poo?
That is one of the first things I'm going to try this weekend.
iagree, in 100* weather i ALWAYS use 20-50 castrol
Same here...
And I agree with the hotter weather thinning out the oil. On mine it did the same thing. It just reads really low and im even running 20-50
x3. I've been running 20-50 in my truck for long time. I drove it quite a bit today, and I'm kind of thinking that is what it is. When I first start up, and drive, its fine, stays right in the middle, even at idle. After the engine gets hot, it drops. I'm betting that is exactly what it is. If I check it with a mech guage and its good, then I'll be happy
thanks guys
