MPG data (Dallas to Denver)

[Romer]

Just for grins I figured out my MPG for my trip from Dallas to Denver. Now it wasn't under optimum conditions. I was averaging between 75-90MPH and I know thats not the most effeicient spped for MPG. So for a 908 mile trip, I averaged 15.9 MPG. I'm assuming thats pretty good based on how I was driving.

I did note the initial segment when I was driving thru Dallas and the north Metro area and was going closed to 75 I averaged 16.9 MPG on that tank. But because that was one tank, there probably is a bigger margin of error.

I wouldn't go over 90 because that wuld have put the engine above 3000 rpm for an extended period of time. The rpm is the rule I use with the 40 2F to prolong its life and minimize wear. I assume it also applies here. Let me know if I am wrong!

Thanks

Thats great economy, considering my wifes 97 s/c gets about 12. Enjoy it.

Ken,

16 hwy is typical for a stock truck. You did pretty good considering the higher speed and it's mostly uphill and your truck will work a little harder up here above 5,000'

>> wouldn't go over 90 because that wuld have put the engine above 3000 rpm <<

You're kidding, right? Going over 90 for an extended period will get you in big trouble most places and that brick has a gigantic radar signature. The 1FZ-FE is a modern DOHC design so keeping it below 3,000 RPM isn't a major concern. The truck's up to the task if you can afford the consequences.

Didn't see one police car from 6:30PM (Oklahoma in a trap) all the way home. Only big trucks out that late. The one in the trap I was warned by flashing headlights.

I also always made sure someone was in front of me going a little faster.

I actually tried to keep it at 79 most of the time. Speed limit was 75.

For my education. The 1FZ-FE should be under what RPM for an extended period of time to avoid excessive wear on the engine. No, not thinking of going 120, but towing up in the mountains. Like up to Eisenhower Tunnel with a load.

That's pretty good Romer. After doing some extensive work on my beater, I'm finally up to around 17 mpg with blower, 4.56's and other crap on it.

Is that possible? How'd you do that? Mine with a turbo and completely unrestrickted exhaust at best gets 15 on the highway. And my gears are stock.

reffug, It's been clocked and verified via GPS for about a month now. I posted that back on one of the older threads too. It's like my beater has breathed a new life. That's why I need to beat on it some more.

Like I said. How'd you do that? What new life? Is their a magical elixer? I would love to get 17 with my truck. Although gas mileage will never become enough of an issue to stop driving my 80. Hey Junk are you going to Paragon Oct. 2? Are you gonna still be there on the 3rd? Might consider coming up and wheeling with you if you are.

I usually try to keep the engine under 4000 rpms for a continous drive, but that's just something I came up with. I don't think there is any magic number, I don't think any more significant wear comes at higher rpms. I run good oil (M1) in mine and just drive it. I'm more worried about overheating when running it hard (Eisenhauer tunner like you mentioned) or going up Floyd Hill, or just starting up I-70 from Denver, all those are 2nd gear 4500rpms+ for many minutes.

I wouldn't worry about any major changes in driving style, it's a fairly new designed engine, they wouldn't be legends if you had to baby them to get 200K miles out of them. Some of the most reliable engines I have ever seen (not just Toyota, all brands) have been in friends cars that they beat the hell out of. Every single time they drove it, they ran it to redline before shifting, never warmed it up, never did any of the nice things you do to a engine, yet they all got close to 200K miles out of seemingly worthless engines/vehicles, and everyone sold them before any problems...as long as there is oil in the engine, I don't think there is alot you can do wrong to it.

I think the newer Cruisers have a rev-limiter on them (Christo mentioned hitting it while wheeling), not sure if our's do, I have hit about 5300 rpms (over redline) accidently, no il-effects. The difference is with the engine in your LX (versus the 40), when you jump on the gas it goes, if you're in snow or mud, you have to be careful, since if you floor it, the rpms jump QUICK, it can't shift fast enough, the time I hit 5300 rpms was in lowrange and I was in drive, the tranny just couldn't shift fast enough to grab the rpms down.

Good Luck...

Romer - if it will help you breath a little easier, I've run my '94 at closer to 4000 rmp and sometimes plus that lugging a 3500 lb trailer plus 7 passengers (ok - 6 of them weighed 100 lbs each soaking wet!) up the Grapevine in SoCal. It doesn't have the altitude that the Ike tunnel has, in fact you are starting at a higher altitude (Denver) than the top of the Grapevine is at 4200. I've run that rpm just to (cough, cough) maintain or lose a little speed up the steeper grades. I've sustained that rpm for 10 minutes or more as I recall. Your rig is capable. Obviously long term consequences????????? I've got 133K on my beast.
