I have a 95 XLT 2.3. When towing my jon boat at highway speed, when placed under a load such as going up an incline or when it down shift's I get a loud chatter that I suspect is from the valve train. A friend recommended putting premium fuel in it. It seems to work! Does using 91 octane harm an engine designed for 87 octane?
At 65-70 MPH, I'm about 1,500 away from redline on the tach with overdrive off when towing. Not sure what my trans or rearend gearing is (to old and disabled to crawl under there.) Would it hurt to turn the OD back on when towing a boat that weigh's about 1,000 lbs total when the terrain level's out? Does it hurt the trans turning OD on and off while driving? Love my little truck and just don't want to cause needless preventable damage if I can help it.
