AnswerWell...that's a good one. The "BEST" gas is probably the most expensive one available at a major refiner's gas station. He puts more effort into that grade than any other grade. So, you pay your money and run the best octane rated fuel with his idea of what is best to stop 'PING', fouling, and varnish formation. So, that is my answer to what is "best". Unfortuanately, it is also the most expensive. BP makes ULTIMATE gas. And it is. Again, it is extremely expensive. So, pay your money and take your chance.

In my cutlass Ciera '89 V6 3.3L, with 210,000 actual miles, I run regular. Or the cheapest I can find. This car has the original engine, (no overhauls)timing chain, injectors. Have replaced alternator once. Belts, hoses, plugs, and spark plug wires at 200K. Oil and filters are changed as a RELIGOUS behavior. I worked for PENNZOIL making their oil for years and BELIEVE IN IT. Use Olds recommedations on weight and FRAM filters. EVERY 3000 miles. DO IT!

I just pulled the injectors and sent them to a guy in NY for cleaning, $15 each and $10 shipping. We'll see about his work.

Old says regular is what you want to run. So, I do. I also put a bottle of TECHRON in the tank twice a year. It is a CHEVRON product and works. Do this in the tank you run RIGHT BEFORE OIL CHANGE as it turns your oil BLACK,BLACK,BLACK. Then change oil and filter.

The Best gas is the BEST you can afford. I refine 300K barrels of oil into fuel eveyday, and I run reqular.


Silly 'thing to do' lately. The idea behind it is to increase as milage. It is also dangerous.

OLD MOTH balls were made from napthalene. Moths didn't like the smell. Neither do I. Liquid napthalene, with no water in it, can help burn rate and help milage. So, somebody thought let's dump these pellets in our tank and get the added benefit. SO, go to WALMART and buy some old moth balls and dump about 6 to 8 each in your tank FOR EACH GALLON OF GAS and it MIGHT help a little. Or, they could clog your fuel filter.

Or, you could screw up and buy the NEW Moth ball made of Chlorobenze. This will help turn your lube oil into dark, nasty looking tea. And/or cause crystals on your injectors if you have them.

As I say, I refine 300K barrels of oil into gas everyday. Don't you think if putting mothballs in your gas was a good thing to do... we would be doing it here in the refinery for you?



If your car is an older vehicle, I do not recomend putting anything other than the cheapest fuel in it. The more expensive fuels clean out your system, and take all the crud, and dislodge it into the fuel filter and the injectors. Creating a costly repair. This has happened to me multiple times on different vehicles. Injectors will run about 80 dollars a piece, and atleast 2 hours worth of time and labor. Also, moth balls WILL destroy your fuel system and clog up the strainer of the fuel pump. Also, When an injector gets clogged, you cant unclog them. You can improve how much fuel passes threw, but they must be rebuilt. I gaurentee that the injectors will clog right back up within about a month

Low freon, bad compressor, bad clutch, bad pressure switch (could be multiple of these), bad switch...the list goes on. Best bet is to take it to a mechanic for a diagnosis.

The best place to find the brake line schematic for a 1995 Cutlass is at a GM dealer. The repair facility would have all of the relevant manuals.
