Where are the dealerships getting their fuel? I know a lot of dealers in the NW Chicago area were not using top tier fuels if they were filling the tank upon purchase. Regardless, I can’t believe the fuel map was programmed so poorly as to not take garbage fuel into account.
FWIW, dealer filled with top tier premium on the test drive at purchase. …. Because I was watching ? Dunno, but he used a card at his select station indicating typical.
Whatever the closest gas station is. For us it's Shell. They will put 87 octane in almost all vehicles at time of sale in most cases, but regardless it shouldn't grenade a modern engine like this. Especially one *designed* for 87.
my 114 ci Harley Davidson has 2 plugs per cylinder lol
Are they different plugs and if you put them in the wrong hole it destroys the engine?
And the R-4360 Wasps I worked on designed in 1941, production in 44 had 56 plugs, 2 per on redundant magnetos for 28 cylinders. Aircraft started using them about WW1. Nutin’ new.
Oh yeah, 56 same plugs.
Don’t these plugs have a different function as opposed to working in parallel? Or did I read the description of operation wrong?
The function description of the plugs is rather long. Essentially they fire off at different times depending on load demand. In the hemi they both fired off each cycle for complete ignition
