I'm going on a 6 hour road trip and running my 85 GS with 67k on the clock at about 70 the whole way. Just doesn't seem like a 30+ year old engine at this rpm for extended periods. Please tell me I'm wrong... it's in great shape, new alternator, waterpump, thermostat, radiator, belts and all hoses. Going to premix and I know the OMP works. I wouldn't even consider doing this with a piston engine, but these seem happy at high revs. Thanks

If it blows up, it probably needed to be rebuilt anyways.

67k not that many miles. Looks like you've done needed maintenance. Maybe take a quart of oil,gallon 50/50 antifreeze and roll,should be fine. Check voltmeter,oil pressure and temp gauges periodically. Most of all,enjoy the ride!

4100 miles - Alaska>Arizona (then another 800 mi to CA and 7stock...) last Fall.
70-80MPH cruise for most of it on 100K mi original (but Loved!) 12A... ran like a Top.
Nice feeling to have spare belts, watch your oil, make sure you aren't doing something silly like driving on 10 yr-old tires (regardless of tread appearance). Go!

Make sure the fluids and filters are fresh. Check the belts for wear and proper tension. Check the tires for any dry rot or any odd wear. Inspect the brake linings, suspension, and lights. Be sure to have fresh spark plugs, wires, cap, and rotor. This will help your mileage and ensure reliability. Be sure to bring a small tool kit just in case. You honestly shouldn't have any issues.

Chris you have my cell if you need any help along the way. I think you are probably good to go based on all the stuff you have addressed lately.

I routinely do 5 hour round trips to RTP and back with no issues and of course 8 hours round trips with a lot of driving in between for DGRR. You should be fine. Relax and enjoy the trip.

why not? 6 hr trip, 70 mph the whole way is no problem for any vehicle, provided it's well maintained. but of course, any vehicle can break down during ANY long distance trip regardless of engine powering it. i trust my 7 to take me anywhere at any time, as well as my 94 corsica w/ 3.1 V6.

Thanks everyone, for some reason I thought you rebuilt your engine Stu. I made it up to VA no real problems. I'll have to double check, but my math tells me I got 23 mpg, very hard to believe since around town I'm usually at 15. Most of the way, had headlights, ac, cruise and stereo going and the alternator kept right up. Gives me a lot of confidence to take other long road trips and without the wife since she hates the car😝

It handles like a dream on smooth concrete roads, except when sandwiched between big rigs.

I get about 24 mpg averaging about 80 mph with my hogged out nikki. Around town its about 17 as well. Around mountains its about 12 LOL!

Maybe we can get you to DGRR next year!

Only recommendation would be to change or at least have on hand a new fuel filter. Using up all the fuel in your tank after not driving it very much can stir up some gunk.

I changed duty stations from Coronado, CA to Jacksonville, FL back in 2000 and my daily driver at that time was my 85 GSL-SE with a little over 100k miles on the odometer. Drove coast to coast with the cruise set at 80 and the A/C on never had a problem, no overheating or battery charging issues and good oil pressure. However, I did wish for a sixth gear to get rpms down for for better fuel mileage but consistently got 24-25 mpg if memory serves me right. That 13b just hummed right down the highway without skipping a beat and seemed very content at that pace.

I bought my first RX-7, 1980 GS gold, with a blown motor back in 1986 while I was in the Navy. Put a low mile engine from a wreak in. Drove that thing from Kansas City to Florida to meet my ship. Went on a six month Med cruse and let the car sit on long-tern parking. When I got back, I got my honorable discharge after six years. The rx-7 fired right up and I drove it from Mayport Florida-Kansas Connecticut without a hitch. Someone T-boned it so I bought a GSL-SE. Sold the engine to someone and we put it in their car.

LA to Vegas and back every summer for four years, up until two years ago. 110+ heat, 85 cruising in 5th gear ~@3500RPM, averaged around 30 MPG round trip as I recall.

Maintain them well and any car can do this; city driving is what kills cars. Constant speed and constant load is the easiest type of wear.

Why did you stop? LOL!

The annual meet I used to go to (What Happens in Vegas) closed down. Then life got busy.

There's a new Vegas meet sprung from the ashes, but last year or so changes at work (promotion) and such have kept me too busy to stay active on the car scene much.

I'll probably only hit SevenStock this year, where I used to do three or four gatherings a year.

Same reason I've been kind of scarce around here lately. Tuit shortage.

I here ya! I used to go to the Mitty, DGRR and a fall get together in the Blue Ridge mtns but now its basically once a year to DGRR for now. Still do as many local cars and coffees and such as I can get away with.

One of my dreams is to drive to sevenstock from NC in my seven. Someday someday ...

I'd love to make the journey to 7Stock from NH. I should probably start with DGRR.

remember "Brian O'Conner (Paul Walker) of Fast n' Furious in the old 9 year old Porsche with the original 9 year old tires? so how old are the tires on a 33 year old car with 67K miles on the odometer? (a good SAT question)
