Definately I'd get 500,000 ot of an H1, and I'm reasonably certain I could do it with an H2, provided I was in charge of the maintenance of the vehicle from day 1. I'm not sure how far I could get an H3 to go. I figure at least 250,000 miles.
If I remember correctly, the chart on the back says it should save you 441$ in fuel savings over the estimated lifespan of your vehicle. I think that number is crap though, becuase it should vary greatly between makes and models, and some cars last forever compared to others. A metro would notice alot more than a H2 Hummer...
A metro OWNER might notice a lot more than an H2 owner, but the reality is that you save much more fuel (as in gallons of gas not burned) by increasing from 8MPG to 9MPG than you do by going from 48MPG to 50MPG.
For example, traveling 10,000 miles in a vehicle that normally gets:
10MPG burns 1000 gallons of fuel, going to 11MPG burns 909 gallons, saving 91 gallons by going up just 1MPG.
20MPG burns 500 gallons of fuel, going to 21MPG burns 476 gallons of fuel, saving just 24 gallons by going up 1MPG.
50MPG burns 200 gallons of fuel, going to 55MPG burns 181 gallons, saving just 19 gallons despite being a 5MPG increase.
The same 5MPG increase when going from 15MPG to 20MPG saves 167 gallons of fuel.
So, if the H2 gets any gain in MPG at all from synthetic oil, it is much more likely to be economical to use it than it is in a Geo Metro or Civic VX.
Thank you. Makes me feel real good I got my truck from 13 MPG to 16 MPG. I'm kinda dissapointed that I haven't gotten any better, but considering that most of my driving is short trip city I guess I'm not doing bad. I've been holding out on filling the tank as the price is dropping 3 to 5 cents per day out here. I think I'm going to fill tonight though. I'm down to 1/8 tank.
Between the falling price and my lack of finances, I've been holding out too. I got as many commutes as I could out of the gas in the truck, and I should be able to get to next Tuesday with what's in the car, unless I do a lot of driving this weekend -- but if I do then I'm probably doing work and making money.
Its falling fast. I looked on the internet. The station I filled up at last week for $2.509 is now $2.119! Its a shame that station is ~100 miles from home. Costco around here is showing @ $2.219 which isn't bad at all. I don't have a Costco membership, but the 7-11 on the same street usually matches the Costco price. I don't like 7-11 gas because they support Chavez. I don't care how expensive gas gets, I choose not support Chavez since he had stated that he could use the price of fuel as a weapon against the US. He's also converting Venezuela into a socialist regime. To tell you how much I'm anti-Chavez right now I'd rather purchase fuel from Cuba than Venezuela.
Anyway, even though its 10 - 20 cents cheaper I have held out and not purchased fuel from 7-11 yet with the exception of Rusty because the only stations within 10 miles of my parent's house are all 7-11's.
Yes, I do mean on the original engine & transmission... Modern automatics last a very long time if maintained properly. Back in the day they used to say if you didn't have problems with the transmission, don't touch it and they usually lasted ~100,000 miles. My dad used to drop the pan on our old Bonneville wagon and change the fluid every year and 13 years and 180,000 miles later that transmission was still running strong. I currently have my automatics professionally flushed every 2 years. which ends up being ~ 20,000 miles on the Beast, 5,000 - 10,000 on the Buick, and less than 5,000 on Rusty.
HC: http://www.qpower.com/ Yup, looks like QuakerState. I always used to use Rottella T 10W-40 Syn, but they only sell by the gallon and it ends up more expensive.
Also I messed up and put Horse Power into the Festy, forgot I got two different bottles! Oh well. Either way the previous oil was a very muddy brown (maybe like coffee with cream and sugar in it) and dino oil and the valves were not getting any lubrication for 10-20 seconds starting on 40F mornings! So I used a fram that's supposed to have an antidrain back checkvalve for quicker pressure and synthetic, no tapping on cold starts, 30F this morning. I use synthetic in the winters in all my vehicles for this reason, in the summers though I've been cheap and used dino in the truck and will probably in the festiva. I've never noticed much MPG difference and only a very slight smoothness, most use it for the pour temperature.
