Mechanical oil pressure gauge.
Posted: Thu Aug 11, 2011 2:17 pm
Hi, I've just installed a mechanical oil pressure guage in my L300. It wasn't as easy as I thought it was going to be but with a bit of cursing and some fiddling I got it sorted. I replaced the tilt guage with the oil guage as I had no other place to put it, hence the fiddling about.
Now I have real time pressure I'm a bit concerned about the initial flash up pressure. It takes about 8-10 seconds to read any pressure then proceeds to about 85psi. After a couple of minutes at idle I start off fairly slowly and the highest I've seen it is 95+ before it warms and settles down to anything between 40 - 65psi at average RPM to maintain 60 - 80kph. At idle when warm it hangs just under 30psi.
These numbers are based on a couple of factors; I'm using Rotella T triple protection 15w-40 and a Fram oil filter, and the average temperature in the morning lately has been about 12 degrees. (185,000 kms).
Do these numbers sound about right?
Thanks very much.
Steve.
