With gas prices getting crazy high. Its time for me to pick up a cap with a lock on it. Heard today at school someone had there car syphon. Not at school but at home. Its getting out of hand. Anybody have one?

I think all Bonnevilles have little screens that prevent siphoning. If not, at least all the 92-99 'Villes have them. A member here had a neighboer use a flexible metal rod to knock out that screen and siphon gas, but very rarely is a gasoline thief so well prepared.

I have a locking gas cap that I keep unlocked. I figure the screen door helps if someone really tries to open the cap. Speaking on non-locking gas caps, some break over time and don't lock anymore. I have never had one break while locked, so that'* good. See if you can get a "good" cap if this is a concern for you.

The last 2 locking gas caps I bought have to be unlocked to open and then relocked once reinstalled. The styles I have used before didn't need to be locked with a key, they locked automatically whenever they were screwed on.
Just throwing this out there.

It is VERY difficult to siphon gas from a 92-99, and probably every other year.

When I started the tear-down on my 93, I couldn't siphon the tank to save my life. I had it up fairly high on jackstands too. I ended up disconnecting the fuel lines at the rail, extending the line into a gas can, then using a jumper on that bypass pigtail near the battery. As soon as the pump changed pitch, shut it down, had about 6 ounces left in the tank. I suppose a crafty gas thief could do this, but wow would that take a set of stones!
FWIW, I was in Germany for a week on business, They're paying about 1.50 euro per liter, if I remember correctly. The exchange rate is about 1.59 right now, so we still got it made.. Lots of bike riders over there, therefore, not many obese people either. Also, I remember in 1979, gas was $1.19 per gallon, so we have tripled the price of gas since then, but mean incomes have gone up more than by a factor of 3. And, cars these days, on average, get 2.5 times the fuel mileage than they did back then. gas is still a bargain if you look at the big picture. We have factory workers here, always bitchin' about the price of gas, but have no problems feeding their 2-pack a day cig habit, or DRIVING every lunch hour to the local convenience store to buy their scratch tickets and pre-fab lunch. I make my lunch the night before and bring it with me, my car sits in the parking lot at work during lunch, and I don't smoke, and I don't play the lottery.. The factory guys spend about... I'd say... 30 bucks per day at lunch time for all this stuff? My average home made lunch costs less than 2 bucks a day... seems to me that 28 bucks per day goes a long way toward the price of gas, and I'm not filling my body with smoke... Just my 2 cents worth, and well off topic here.. Sorry Willwren..

I thought all SLE'* and SSEi'* of 2000+ had locking gas doors?

mine does.

A few weeks ago Pmom had the gas cap stolen in bone evil, they didnt get any gas but the cap was gone.

Only $4 more at Napa for a locking one.

My 2000 SE locks the gas door when I look the passenger doors.

Jim:
By 2004 the locking gas cover had been removed as a cost savings item.

And the locking gas door is more of an inconvenience to a thief, its not security item in my view.
