1997 V10 mpg
I'm sure this is an old topic, but being new to this forum, I need help. I just bought a 26' class c motor home with the V10. The owner represented the MPG at 9-11. Driving it to Tennesse from Texas I got 7.2- 7.5.
About 2/3 the way home I replaced the air filter with a K&N, which got me to 8.0. Still a dissapointment. Any suggestions on modifactions or changes that will improve the MPG. The engine has 61K miles and runs well with good power.
Thanks, Don T.

Little if any.
But, I would go back to the 5w30.
It never ceases to amaze me why the old thought of thicker oil still stands.
Closer tolerances calls for thinner oils. Thicker oils never get into the critical areas on these newer engines.

No, changeing oil will not improve your MPG. I have a 2003 F-250 and I average about 11 mpg. You have to figure that your motor home, is going to experience more wind resistance than a normal V-10 truck and it is heavier also. So I think you are right on par getting about 8 gallons. That is about what I get when I tow my boat.

Get a big, long iron bar with a hook on the end. Creep up behind a semi, and latch on like a remora on a shark. He'll never even know you are there. Outstanding mileage!

Yes changing weight will change your milage. I experienced this first hand with my first V10. I started with 5-30 an averaged 14 mpg unloaded and switched to heavier 10-30 and lost 3 mpg! I thought the heavier oil would help, but after seeing the gas prices rise i went back to 5-30 an change every 3k miles. YES IT WILL CHANGE YOUR MILAGE!
