')Sure. Equipment:
05 Civic VP Coupe
4cyl engine
5 sp manual
No power options
A/C
Tires are at 45psi (max side wall pressure is 51psi)
EPA sticker: 32/38
Current mileage: 43500
I simply coast and drive very slowly, seldom over 65 mph, lots of engine-offs at stoplights. I cycle the a/c in the summer, not running it full blast. I push my car out of the garage and roll it in neutral 1/10 mile to first stop sign (it's all downhill). When I park, I try to park in places where I don't have to back out or I can roll backwards with gravity. Oil changes every 3k miles. Last 5 months of driving(7300 miles) I've averaged between 45 and 50 mpg. Best tank: 55mpg. Worst tank: 39 mpg.
I also have an 92 Accord, 4cyl, 5 spd, 196k that I hypermile to 36mpg average (24/30 EPA sticker)
I personally think hybrids are a joke. Look at the prices: 05 Civic VP: $14k, 05 Civic Hybrid : $20k(?) Big waste of money to pay more for same mileage!!
I get the same mileage or similar with some conservative driving, not extreme or unsafe methods some guys use. Although I guess one could argue I could probably get 70+mpg with my techniques on a hybrid, what about the batteries life time? Am I going to get to hit with a few $k after I put 100k on a hybrid to replace them? Wouldn't that just obliterate whatever savings I had with fuel economy had I just stuck with a traditional 4cyl gas manual? I'm satisfied with my mileage and figure I'm still way better off than the person (with questionable intelligence or concern for the future) driving a humongo SUV.
Not to argue with your post (other than the part about the SUV, some people actually use these for more than just a one-butt hauler), but I have an observation for you. You're changing your oil every 3K miles and it's completely unnecessary. I have rebuilt many engines, worked on cars all my life, and 3k oil changes with today's oil is unnecessary. Your tire pressure is way high. You're tossing all your savings.
You've driven 7300 miles at 45mpg average, and sticker was lets say 35mpg average.
7300/45mpg =162 gallons. 7300/35mpg = 208 gallons. Savings of 46 gallons of gas. At $2/gallon, that's $92. Now you've got at least one extra oil change in there (a reasonable oil change schedule is 7500 miles unless you're in the desert) and if you don't do it yourself, that's 30 bucks. Now your tire pressure settings are about 15psi above recommendations. That's going to create a crown in your tire, meaning you're going to wear the middle of the tire out faster. Each psi above recommended for car (based on weight, distribution, and payload allowances) is going to be about 1% faster wear. So you're wearing your tires 15% faster. Let's say tires cost $400 for 4, mounted & balanced. You're only getting $340 worth of wear out of those tires.
Anyway, if you start running the numbers, you find that you're not saving as much money as you think you are, nevermind the inconvenience of pushing the car out of the garage and driving in a vehicle that handles like a rock because of overinflation.
Thanks for your thoughts. However, I will debate a few things.
#1. Your oil change philosophy is right on, however, I *am* in the desert, so I choose to err on the side of caution until my warranty expires at least. I will probably stretch to 4k or 5k miles on my next oil change.
#2 I have read several articles about just what is proper tire inflation, it's debatable on tire wear but the tires are wearing just fine. I've 43k miles on them and should get another 10k or so, so with 55k on a set of tires, I'm not complaining. I'm a frugal shopper and will probably find tires much less expensive than your $400 number.
#3 Most of my driving experience does see SUVs as one-butt haulers, especially in stop/go traffic...
#4 I have driven many sports cars (former 'Vette owner) and don't mind the (subjective) rougher ride. It's still way softer than my old 5 series BMW. I also don't mind the pushing....I can consider it a challenge to increase my fuel mileage and so far I'm way ahead with my costs.
I agree with you, with today's ludricrous gas prices, I'm not saving much as much when it was $4/gal, but I feel like at least I'm conserving when most people aren't. As some people want to go faster/faster/higher hp, etc., I want to go with less/less fuel.
