Octane rating

[drewactual]

the diesels i've worked with lately have bedplates as opposed to individual mains.... and THAT is the way to go when pushing. the strength it gives is far superior.... which it would have to be. the static compression of the 6.4 is 17.5:1, and i can tickle 60# of boost and see as much as 40# daily which means cylinder pressure and the push against that bedplate is friggin' ridiculous at times.

the windsor 5.4 block or the one built in Michigan have these differences, i'm learning. the 8 bolt one is independent mains, where the six bolt one is a girdle? ...... again, I'm just starting to dig into the facts and have never flip one over on a stand to see for myself..... yet...

i've sure hijacked this thread good, no? apologies.....

I've used 87 octane for years and put in a bottle of Techron Max every 10,000 miles - or oil change. Works like a charm.

How do you get additives in that capless tank??

I tried it somehow just spilled down the inside of my fender and made a mess. Ugh.

You have to use the plastic funnel that's stored with the jack. It is the right size to release flap just like the gas nozzle.

Its not required its recommended. And the Expedition is in no way a fleet vehicle. You probably cant name one company that owns a fleet of 15+ Expeditions

Also, I've heard of disgruntled livery companies ditching the fullsize GMs for Expeditions over tranny issues with recent batches requiring tranny swaps every 100-120k miles....

Some previous owner jacked mine, pardon the pun

LOL, you can buy them from the parts department at Ford but I would think by now the Auto parts stores might have them.

I'm sorry but what's your point? There are millions of products produced with someone or something "in mind" that never get used for those intended purposes. Again show me a police force or fire dept that runs a fleet of 17 model Expeditions. I'll be waiting patiently

Look at the pic.

'17 SSVs get the old-style bumpers.

You wouldn't be able to tell if you saw it.

I've been absent here for years but just upgraded my '07 to a new '17 Expedition XLT. Any benefit to running 89 octane over 87? I'll no doubt run 93 when towing but it's a 75¢ bump here in Ohio. I run it in my S2000 but premium is required in that 'lil car.

I picked a '17 rather than wait for the '18s to cut any learning curve.

I have a 2015 Expediton Limited 4x4 - and I use 89 octane fuel. I used 87 octane (recommended) for the first 5-6,000 miles and then switched to the 89 octane. I kept track of my fuel mileage as my driving routes and habits didn't change. I get about 1.5 more mpg with the 89 octane. When I take a long expressway trip with passengers and the a/c (vacation...), I use premium fuel even though I do not tow. The vehicle is used exclusively for passenger use - never towed with it although it has the HD towing package.

I'm in southern Ohio and the price bump is about 50 - 80 cents for premium (25 - 40 cents for mid-grade). I was out today and noticed that 87 octane had dropped to $1.93 a gallon near where I live. Amazing.

How do yo like the 3.5 Ecoboost? I really like the engine. This was my first Ford purchase in over 40+ years of driving.
