hello

[Milo2361]

hello everyone, my name is miles im a first time poster here. I recently bought a 1980 porsche 911SC. A dream come true. I was wondering if E-10 unleaded gasoline would be compatible with it. Dealer said its fine for regular unleaded but i forgot to ask about e-10 (its about 30 cents cheaper than regular unleaded here )

thanks,
miles

Welcome! Spend the extra money for real gas while you can. E-X will have adverse effects over time on our cars.

As long as you do not experience detonation, which you will probably not on the street, regular gas should be fine. Any ethanol will be bad for the fuel system. It, being polar molecules, can dislodge the deposits from the years of non-polar hydrocarbon molecules running through it.

If you upgrade the motor in the future with higher compression or want to advance the timing, you will need to twin plug and run higher octane gas.

Welcome!! PICS, PICS, PICS!!!

[Milo2361]

wow you guys are quick thank's for the info. so far I've only used 91 octane.

ill post some pics as soon as i can. 117,XXX miles when i bought it, about 119,xxx now immaculate interior, no oil leaks doesn't burn oil. rides like a dream!

[GH85Carrera]

No oil leaks. That is different in a car that old. Stay away from ethanol if possible. Your fuel system will thank you in the long run.

Welcom to the board!

Welcome to Pelican and congrats. I am also new here. There isn't a project I've done, which is actually quite a few for someone that didn't ever work on cars, that I haven't had help from the great people here. But before you get shunned like a rabid dog you bess post a few pics of your baby!!!

You should return this car to the factory, they must have forgotten to put the leaks in, or perhaps you have "The One"....wait.... maybe its ran itself dry and you have no oil in the engine.

Congratulations on your car and welcome to the board.

Remember to use lots of smileys in your posts.

and post pic when you can.

[Zeke]

Yes, the "unofficial" rule is that 1st time members must post a pic of their car.

Welcome, nevertheless, to our community. Sounds like you have a fine car. Maybe you should post pics of the underside of the motor!!

Mine doesn't leak either.... until I start it.

[450knotOffice]

Welcome to the best and largest Porsche forum on the planet! Pics please.

[Milo2361]

ill have her cleaned up this weekend and ill take some pics for you guys. this one is a cell phone pic. not great quality but its a start. (dont mind the 02 GMC sierra.... that's my dads haha)

got a little chip in the right fender - - crappy touched up paint(not noticeable from 10ft, maybe the size of a quarter) a little ding on the sunroof, and the usual rock chips in the front..... not sure what car that has been driven 100k miles doesn't have these... heck on the drive home from denver, people in Lexuses and other porsches were havin a look
i believe it is the original paint, and the garage floor under it is dry so I'm pretty sure nothing is leaking..... at least to the ground anyway. dipstick has stayed the same the 2000 miles I've driven it so I'm confidant it doesn't burn or leak... maybe just not enough to notice because i hear they ALL leak.

[snbush67]

Congatulations, Cool car!!!

Make sure you check the oil with the engine warmed up and running on a level surface.

[Milo2361]

just curious, but y'all getting decent gas-mileage with your SCs? cuz i hate to say it, but i expected better. - - but perhaps not having a working cruise control might throw it off a couple mpg.
i got 23 on the way back from Denver at about 80mph, and so far, with mostly in-town driving I've gotten 16-19mpg.... that about average?

[Gordo2]

Congratulations, looks like a great car.

Not to start a sideline discussion on your thread, but I run 87 octane in my '83 SC without any signs of detonation. The stock compression (9.3:1) ratio for these engines allows you to run regular fuel - that's why your manual recommends regular BTW.

It won't hurt to run higher octane (other than in the wallet), but I don't think it is necessary or beneficial in any way other than providing peace of mind.


Good luck, Gordo

Nice looking car and welcome to the board. I use Chevron Techron 92 Octane. I know I don't "need" to, but my baby likes it. Regarding milage, I get about 25 on the highway, and about 18 or 19 mpg city. I could probably get more if I could keep my foot off that pedal.

[Milo2361]

oh... thats sort of a relief on the gas mileage. all of our stations with 87 octane are e-10... 85 is regular gas, 91 is regular gas. i got some 85 octane and put some of that octane booster stuff in it ($1.50/bottle... figured i'd try it) - - if it gets me up to 91 octane its cheaper than paying for a full tank of 91...

haha i have a hard time keepin my foot off the gas too. driving a '70 VW beetle then changing over to this... talk about satisfying
