2002 Overland, 126,000 miles
changed my oil last night after a 1200 mile trip towing a 5000 lb trailer. Put in 5.5 qts of Mobil 1 10W30 High Mileage (same oil I've been running for quite some time) and a Mobil 1 M1-204 Extended Life Filter (normally I run a Bosch 3402 for 3000 miles and change oil at 6000 but the Mobil filter was on sale).
Immediately after the oil change I noticed the oil pressure guage sitting at the 3/4 mark most of the time. It fluctuates slightly as would be expected, but is always above 1/2. Oil level is fine.
From other posts it sounds like this is probably an oil pressure sending unit issue, but it seemed strangely coincident that it happened immediately after the oil change. Am I running any risk by driving it for a while and keeping an eye on it to see if it returns to normal? This weekend is the soonest I'd be able to get around to the sending unit.
