hoochWhat's the price spread between gas and diesel in your area?
Around mid Michigan it's anywhere from 80 cents to as far as $1.20. I can't remember it being that much ever before. My poor Superduty is feeling a bit neglected, as much as I enjoy driving it I don't really need to at this time so I let it sit to save money.

regular gas vs. diesel, around 65-70 cents.

nhracecraftDiesel is somewhere between 7 cents higher and dead even depending on the station, and I generally buy at the one with the lower price as all are within a couple of miles from my house. All four of the vehicles in our household require Premium though, so that's not too bad I'd say.

tatortoddThe lowest top-tier regular unlead vs diesel spread is $0.70 but then again it's refined here so less logistics risks.
The last few years premium unleaded and diesel have had similar prices around here, but right now diesel is 32-70 cents lower at top-tier stations.

Oat_Action_Man3.29 vs. 4.19, gas vs. diesel. Prices have held unfortunately steady for months now.
Gas dipped for a few days, but diesel has stayed that price.

vthoky“Regular” gas here this morning was $2.72; diesel was $3.39.
Like nhracecraft’s situation, the difference between premium and diesel is negligible.
I love that the question has been asked! It makes me feel just a little less nerdy for having tracked and graphed local gas/diesel prices for about three years now.

Politicians seem to have forgotten that they work for us, not the other way around.

joel9507Per the Gas Buddy app, the lowest cost diesel nearby is $3.35 while the lowest cost regular gas is $2.58, so the spread is roughly $0.77 here.
