Jiffy Lube would own that car if it was mine. They clearly did something wrong. Talk to them, if they don't talk than get a lawyer. They should offer lifetime free service. Oil sampling. Repairs if needed due to oil usage or bearing damage. rental car coverage if needed. All covered for lifetime. Losing an engine at high speed can be very dangerous.

Run flats do have stiffer side walls which will result in a stiffer ride, agreed. Is there a chart or formula to determine rolling resistance for tires?

What you both say is true. My stock Michelins green X weight 22 pounds each and the #1 rated "run flat" at tire rack, the same size, weight 28 pounds each. Is there other differences? The #1 rated run flat is also less money than a Michelin Green X. Don't think I could have a jack,spare, etc for the 24 pounds increase in rolling resistance. What am I leaving out of this puzzle?

I am new here and have a new Fusion Hybrid in the garage with 11 miles on it. I have seen a couple of threads about donut spares but my thinking is run flat tires. While my tires are still basically new I am talking to a couple of tire dealers about trading for run flats. My questions: 1. Should run flats be standard equipment or an option? 2. Is anybody doing this? I use to own a C5 Corvette and run flats came standard on the car. Investing in a Hybrid means reducing the weight of a jack, spare, air compressor, etc. Run flat tires are not that much more money for the security benefits. Any thoughts?

yes it should be 2016. My Fusion Hybrid Titanium was built 2/19/2016.

A compression release engine brake, frequently called a Jake brake or Jacobs brake, is an engine braking mechanism installed on some diesel engines. When activated, it opens exhaustvalves in the cylinders after the compression cycle, releasing the compressed air trapped in the cylinders, and slowing the vehicle.

L is something like putting the engine into a Jake Brake mode? True?

That helps me understand, so, moving the gear selector into L is not changing gears but telling the computer to remap the engine for a decent. Right?

The Fusion has a CVT transmission, so why is there a D, L and R on the gear selector. If its a CVT should it just have D and R? How can a CVT have 2 ranges?
