Hi,
With fuel prices going through the roof, is it time to "chip" the V-10 engine with the idea of saving fuel? RV is from 2004 so a four speed.
I do drive 49 mph (78 kph) and do get 8 to 10 MPG doing so.
I can not afford a replacement engine, so I do not wish to take any risks.
Today, here in California (Los Angeles area), I just bought Chevron (Pearson Fuels) E85 for $3.85 a gallon. (over 100 octane fuel) Regular 87 octane fuel was $5.50 at the same station. Do the math. See what works best for you. I've used up to a 30%/70% mix of E85/87 octane in my 1999 Class A F53 V10 with no drivability issues. There is a slight hit in the fuel mileage, but hey, . . . at 7 to 9 mpg already, that's not what's bunching my undies.
Chip tuning for economy/power (while meeting emission standards), . . . . please, . . . tell me when to stop laughing. IMO, these "chip tuning experts" will never beat the Ford factory engineers with repeating reliable verifiable data. It's all marketing and advertising XXXXX.
