Does V10 require premium
 

Looking strongly at V10 versus diesel and need to know does the V10 require premium gas or can it run on regular? Did a search but nothing showed up

Thanks don

My owners manual says 87 octane and that's what I run, no problems. I've heard others say that if you do a performance chip modification it may require you to run a higher octane depending on your setting.

I put 220,000 miles on mine with the chepest gas i could find and never had a fuel problem. I changed the filter once at 170,000.

it requires 85 octane minimum. so yes just cheap gas.

Yup, use "regular" - that's either 85 or 87 depending on where you live.

The motor is made for it. I never used anything but 87 in my '01 V10.

In my '96 t-bird 4.6L, I used to run "Super" or 93 even before I put in the Superchips. I ran 87 a few times (w/out chip) as a test, and found that 87 was MUCH better for it.

How? In cold drivability. Cold starts especially. It always seemed to misfire once or twice on cold startups with 93 octane (even w/the chip). 87, fired right up, ready and willing. Also, with 93, it seemed to run "lean" at idle and off-idle (like just touching the gas to get going).

What this means is high octane runs colder than "regular" given the same motor. So, to fix it, running a litter richer when it's cold out might help, but why bother? Just run the cheapo stuff.

I'm lucky - I have a good, clean, decent guy running a station a few blocks from me, and happens to have the lowest priced gas around and all my vehicles run great on it. Turns out, they seem to run lean/cold on Amoco/BP (expensive), but run great on the local Gulf, both 87 octane. The Amoco/BP probably has a higher octane than 87 (or the cheapo stuff is really 85).

I always ran Amoco/BP in my '96 t-bird 4.6L and the fuel filter was just as bad as my wife's 97 cougar 4.6L (local Gulf) at 20K miles. Matter of fact, that '96 saw 20K miles in the first 2 years. The wife's car just broke 20K after 8 years. Which probably means the Gulf is even cleaner than the BP, having 8 years of varnish in the filter.

Anyway, I'm rambling... ;)

does the V10 require premium ? I disagree
 

it does require premium, premium owners/drivers. This aint no puddle jumping, low-tech small block chebbie. It requires a person of higher intellect than one that would,,, say,,,drive a dodge. It's a different animal, it's a ***** cat when you want it to be. But you lay into that fuel metering device on the floorboard and you'll get the claws baby. Women will shriek in disbelief, young children will cry, pick-em drivers of lesser makes are humbled. Yep, it does take premium, but regular unleaded it runs on just fine. :-X07

Good reply ken04, I like that. Thanks to all for your answers.

:) The owners manual for my 02 V-10 calls for regular 87, it also goes further and states not to use the 85 that is found in some parts of the country.

If I remeber correctly someone did a dyno and 1 truck had premium and 1 regular and both trucks ran the same.

When you get out west in the higher altitudes all you can find is 85 octane, and they run fine on it just so long as you are at high altitudes. You have to just plan your trip so you can get ride of it before come down, if you don't it will ping like crazy.

twas me
 

the dyno pulls were made by nisar and i. mine with a load of 93 amoco ran worse.
as to grade the owners manual states 87 . and thats all i'm running even with the engine retuned almost to the max sct can set it at. no pings or any thing.
hay ken is the van different? in the manual?
and thinking of mike he's been mia for a while. has not posted in a long time

[QUOTE=rvpuller]When I travel in the high country I always use the mid grade 87 or 88 octane. I have noticed in recent years a lot of stations do not even carry the 85 or 86 any more. This is mostly true in areas where there are large numbers of tourists. This was true in and around Jackson Hole and Yellowstone NP. It may cost a little more to keep the octane up but for a few days or weeks ill do it, that way don't have to worry when I start going down hill.

The book sez 87 Octane for my 06 V10. It does fine even when pulling an 8K trailer. (My buddy has a foreign car that requires premium. Drives him crazy that I have a engine that creates considerable more HP and uses 87 Octane! Life is good.)

most be from germany! almost every one driving a vw has reg. gas in it even when the gas tank door states 91 and owners manual states it also
