Ok, so let's say 150 miles a week? That's filling up ever 2 weeks or so.
300 miles to a tank … ?

Damn, I better get my foot booked in for a service as something must be wrong with it … :giggle:

Be grateful, if my maths is correct its currently $9.55 per gallon for super (v-Power) here in the UK!!!

£1.58 per Litre.

Its getting rather depressing filling up! but still use V-Power.
Yeah, my 14 (large U.K.) mpg is getting fed with V-Power … :crazy:

This brings up a question that I don't know the answer to. If I have a 91/93 tune from Lund and put in 87 will anything bad happen or will the tune adjust?
Bad things, very bad things. The tune will not adjust. Just don't do it.

on my 2014 3.7 i ran an 87 mpt tune, and it knocked like all hell on 87. so no nothing adjusted in it’s own back then. i had to run 91 to get rid of the knock. they claimed thats never happened before on their tunes so by the 4th revision it didn’t knock, but it felt almost identical to stock. totally worth 400 bucks….🙄🙄🙄🙄

The tune won't adjust but if you're gentle it should be okay. I was on a road trip (spur of the moment) out in butt f**k no where and needed a fill up. Only station was some run down, abandoned station with 87 in some backwoods town. I have a 93 tune but it was that or get stranded. I drove her like grandma Jenkins drives her camry and didn't experience any knock. But you bet your sweet tush I drowned my tank with fuel cleaner when I got back. Now if you dump in 87 and drive it on race day then you may find yourself with a hole through one of your pistons.

The tune should very much adjust, unless Lund specifically turns that aspect off which is terrible.

Stock tune can go -10 or +10 in timing over the base map, so it should definitely adjust. It won't run great, but it also won't put a hole in your piston.

You also paid for 460hp, but you only get <450hp on regular.

Do you like buying stuff and not getting everything you paid for?
Oh no. Does that mean I have to carry 2,000 lbs in the bed of my pickup all the time because I paid for that capacity?

I think 87 in winter on winter tires isn't going to be your limiting issue for power :)

Summer? Yeah I put 91 (Canada) or occasionally 94 even daily driving but that's because I know the day I don't, I'll get into a rolling race and be kicking myself I didn't have the best possible fuel and that'll ruin my week because I obsess like that :)

EDIT to add your money, you earned it the hard way, you get to spend it any way you want.

I run Petro 94 as much as possible. It's up to $1.75 / L in my area ($6.60 CAD/$5.10 USD per US gallon) but I figure I bust my ass to earn it and I can't take it with me, so why not?
If I can't get 94, I'll run Shell 91.

It's not "terrible." It's kind of the idea. Comparing the stock tune to a 93 oct tune doesn't work. The stock tune is specifically calibrated to run at both ends. The downside to that is if any knock is detected it retards your engine as if you had 87 in the tank. In my case, it took forever for the stock tune to adjust even though I only ever ran 93. It felt completely neutered at the low end about 70% of the time. The 93 tune fixed that issue. It'll still retard the timing if there's knock, sure, but not enough to make it safe to run 87 and go all out. If it did then what would be the point? Just stay stock. It's not like a 93 tune will gain much performance on its own.

I use 87 normally and on rare occasions put in 91… If I know I’m going to be able to drive hard a decent amount.
