[Lesey]

Hi
I need some adcice from the members. I own a '71' 1600 twinport Luxury Germin Vehicle (you call it a bug) The motor is still standerd with oil air filter and all. Somebody told me today that I must not use Super petrol in the vehicle but the normal unleaded. He said the motor will run cooler searched the site but did not find any info This is my first aircooled vehicle So please give me the correct I dont want to damidge the motor. Love the site and my NEW old Luxury Germin Vehicle

Run normal unleaded. Try to use a tank of LRP every 3 or 4 tanks...

The Aircooled engine was designed to run on Unleaded.... Ok they didn't know about Unleaded back then but hay the man knew what he was doing... You can run the Unleaded fuel and like Tony said use some LRP now and then....

Not all of them can run on unleaded... but if you have a early 50's or late 40's engine, it might be time for a rebuild.

Dont worry Lesey, yours is safe for unleaded

I cant remember dates, but I think every engine after the early 50's was made with stainless steel seats (or another hard steel) which is unleaded safe. Its only the very early bugs that had cast iron seats and its those that need leaded fuel

Thanks alot. for all. The first on me when we meet.

The idea of all later heads are good to run unleaded is not so clear cut. I can assure you that many of the rebuilt heads locally that got new seats were never replaced with hardened steel. Mc Donalds Engineering one of the last few AC specialists and still doing extensive AC repairs never replaced seats with the hardened item, they were not the only ones. You need to remember that the price diff. between the two is substancial, and there was no need to fit the more pricey item up untill a few years ago.

good point

[vader]

I was gonna say that but I was running a new Trimixture in my suit and was too spaced out to care...

[Lesey]

I have sum more info according to the motor number mine is a factory rebuild(Have been surfing the site a lot) . So the safest option is to stick to LRP Fuel then the motor will last.

F*&k the environment....

[bugspray]

Are you guys saying that I can Use UNleaded fuel in my 75 beetle?? Would'nt it cause detonation and kak?? 75 std beetle not rebuilt engine.

[vader]

Yip thats what we saying...

[bugspray]

Just follow the advice above and you will be A ok....
If I can get my gas mixture correct I might remember if you need to advance your timing or not.... But maybe Chrome Dome can help with some info...

[Tony Z]
