Premium is the New Regular: Automakers Want to Kill 87 Octane

The automotive industry wants to make 95 octane gasoline the new normal for the United States and it has taken its case to Washington. On Friday, Dan Nicholson, General Motors’ vice president of global propulsion systems, told the House Energy and Commerce Committee’s environment subcommittee that switching to 95 octane would align the U.S. with Europe and is one of the most affordable ways to boost fuel economy and lower greenhouse emissions.

Affordable for automakers, that is. Because there is no reason to think your local gas station will suddenly do you a solid and price 95 octane lower just because 87 is gone.

Sajeev,
Brett here. Got a weird one, or maybe it is not that weird since it involves a Chrysler product and electrical gremlins. My father drives a 2006 Jeep Commander, 5.7-liter HEMI, basically loaded.

Imagine that, a Chrysler product with electrical problems…

Piston Slap: Sucking At Fluid Changes?

Hi Sajeev,

I do a more through job at the time of purchase, but every year after I do a drain/refill on the radiator and replace some transmission fluid by using my fluid extractor to vacuum up as much ATF as possible through the dipstick tube.

I know that I’m not getting all the fluids exchanged this way, but my question is how much of a positive impact is this regiment actually having on my cars? Am I just wasting my time? I haven’t suffered a mechanical failure since I started doing this, but I don’t know if that proves much.

Keep in mind that the vehicles I tend to own are 20 to 30 years old.

  • SPPPP Nice vehicle. My only fear with driving it so little is rodent damage - but I guess keeping it in the garage cuts that risk down a lot.
  • Ajla I think the LS500h should be fine but it is a fancier price point and very thin on the ground .
  • Kwik_Shift_Pro4X Save your money and just keep the car.
  • MaintenanceCosts Good stuff. I miss my LS, although it was not as bulletproof as your GS has been, having experienced suspension issues and a premature water pump leak. Lexus knows how to do a comfy sedan.
