Old school cars, especially with modified motors are much more sensitive to this. If I get a bad batch in the coupe the main symptoms are it'll run a bit rough, maybe ping or just be down on power. I might experience all 3. There are a lot of variables in fuel quality these days. I run the coupe only on BP Ultimate and fill up only at high turnover servos.

Yep I'm the same as you, BP premium is by far the best fuel, I have tried premiums from every other servo and they just seem like normal fuel, I get the same economy and really don't notice any performance gain, with BP fuels I do notice the difference.

I remember reading that the reason we have unleaded is less to do with health and safety and more about it is what the oil companies made the most profit from, why else would they give ua a fuel that is a known carcinogen ?
oil companies say jump .....govco says how high sirs. Ethanol as we already know is not good for older cars unless they are built for it, causing deteriorating fuel line/parts., also has different properties causing engine tune issues for some cars. |

Thin oil is better for making petrol but not engine oil. We hear in aus have mainly thin oil under the ground. As far as better fuel goes leaded petrol was better health wise as a fuel but could not be used with cats and that's the main problem with it and unleaded is far worse for your health, you can't be posioned by breathing in the lead in fuel but unleaded you can get very sick directly and don't wash your hands in unleaded it's that bad as it has deadly stuff in it that can get into your blood but leaded and E10 is not as bad to was your hands in. Leaded as far as a engine goes leaves deposits on pistons chambers and plugs unleaded is much better in that regard anyday. |

When I do take it for a spin I first go to the servo and fill a jerry can with the highest octane fuel I can get, then add an octane booster to that, then add that to the tank and leave it to sit for a while while I shake the back end to mix it all around. Starts first time and seems to go 'ok'.... I baby it along till the pipes get the fresher fuel through then give it a bit of a squirt.... Drive it around for a bit to 'keep it going' and when I return there is 4-5 litres gone from the tank ready for the next time I decide to take it out and repeat the process with the jerry can once again. Actually... now that I got some free time I should jump her and take her for a spin. Perhaps tomorrow I used to be a member of a car club and a guy had a car sitting for ages (years??) before a restoration, then spent big on body and mechanical only to neglect the stale fuel. First time it ran was a track day and the motor blew because what it was ingesting certainly wasn't anything that resembled 'fuel'...

I'm talking about petrol. Volatile aromatics is probably the "good stuff" I was referring to and couldn't remember at midnight.... The crud that's left wont run your car properly, that's for sure. I don't use ANY additives...ever I have been told (not actually done) that to store petrol for long periods in cars/boats/mowers etc it is good idea to put in some two stroke oil and it wont go off as badly. |

New to the site recon it's great so much info,,, hope I can add to that in the future to repay the favour......
Not a fuel expert fella's but just like my lawn mower I start my car's regularly and never had a problem touch wood,,,,no additives just add juice and keep the tank's around half full,,,May be wrong but I think most of the issues is letting the small amount in the carboy sit and turn to crap...

Bad fuel is noticeable by - Engine hard to start; at first cranking times are longer before firing. Smell; off fuel gives off a distinctive foul odour. Extreme cases; a varnish like deposit coats everything - fuel lines, pump, injectors. Normally noticeable on duel fuel vehicles that have near empty petrol tanks for 3 months or longer.

Meaning I didn't see it because I wasn't around? I don't need to be around in the 70s/80s to realise the problem would have been worse in our capital city when cars didn't have emissions regulations and technology was basic compared to what it is today lol. |

You are right, there are alot of specs for petrol and deisel to meet. Some of those specs are colour, vapourability, appearance etc etc. As far as I know, there is not one spec on the power to weight (litre) ratio or BTU (litre). These specs may be set by the petrol companies, but they would obviously be diluted over time. The refining process tends to take stuff out (although they do add some stuff), thus they are refining what they start with, and what they are starting with has deteriorated in the last few decades.

I travelled to Sydney from BHP Newcastle through the 70's and nothing like los angles in the 80's. That not the same pollution related to lead and diesel dust you get in suburb houses lined up along open streets before sound deflection and motorways.

When I was a boy-the local fuel was transferred around outside of large centers around in drums and the quality was variable.
By the end of the 70's I was eaning money fixing and cleaning carby and decoking heads directly created from the technology of the time. But the cars ran on questionable fuel. heavy machinery ran on what you could find. didn't say they did it well but as it was cheep--- Its a good thing that engines are better now-but it would be nice if they could be made to cope with dodgy fuel much better than had done in the recent past.

So far from the truth, Federal government legislated the end of lead being added to petrol, same as banning lead from paint for health reasons only, nothing to do with petroleum companies as adding lead is a cheaper option for them in production.

A well maintained machine will hardly give a problem. Most users do not realise that fuel has a use by date, or that the fuel pump is in the tank and requires a decent level of fuel to keep cool. They run their cars tank to the last litre, cooking the fuel and overheating the pump. They run duel fuel, driving on LPG 90% of the time with just enough unleaded in the tank to cook, shake and brew while they drive around.

Unleaded fuel was only one of many changes brought in, and was required for the Catalytic Convertors. I think that the first change was the Positive Crankcase Ventilation valve, doing away with a pipe coming out the rocker cover and pointing down to the road. Australia was just following other nations, and we were way behind. Missing out on some great engines. http://www.newton.dep.anl.gov/askasc...9/gen99615.htm Quote:

I still think EFI is the way to go tho because it can measure fuel loads much better and maybe even save some?. Last edited by GASWAGON; 30-06-2014 at 07:43 PM. |

Theoretically, multiple well-adjusted carbies will get very close to EFI, but like anything computers simply do it far more accurately. |

How come big 4X Diesels with worn engines can spew out clouds of black smoke.Have diesels got an effective cat.con.that should cut out the pollution.Undercover car-parks are a health hazard when they idle with air-conditioner on for 1/2 hour.Should be a law against it!

All vehicle exhausts are not good for us, diesel has been proven to be worse. Hence the introduction of tougher emission laws for diesel. I hate when there's one in front & cant be passed.

Depends on what expert you talk to.
years ago diesel was seen as saving the world from oil use-NOX -and photo chemical smog. so it was then decided that particulate emission was worse. But is it? or is electric systems need all the help they can. I don't have a university degree so I cant offer the opinion that particulate emision are an issue for a diesel idling in underground car parks. Diesels engines also run catalyst convertors. More common in Australia at this time as hydrocarbon and oxides of nitrogen are more of a health worry that dust. Partical filters or scrubbers have been around for years. Lot of people complain about the smell and the smoke don't understand that its the DPF self cleaning. 4X blowing black smoke--we all know that its not because of worn rings and injectors-like a quiet harley-Its just that the operators don't believe in the opinions offered by those in our employment that cant decide on what is fact or opinion. We all know dozens of people that have had the $5000 threat-does anyone know someone that actually had to pay it? claimed that fuel in the 1930's was bad.

I'm pretty sure to roll coal with a diesel you need lots and lots of unburnt fuel, it just goes out the exhaust as a massive cloud of black smoke. |

No. Modern fuels are produced to a tighter quality standard and have significant health and environmental benefits over older fuels, whilst maintaining required combustion properties.
Today, refineries produce fuels with significantly lower levels of sulphur and benzenes (and that is even before we start talking about the removal of lead). In more recent times (mid-2000), national legislation has seen a reduction of sulphur from 500 ppm to 50 ppm. Benzene levels in petrol have reduced from around 5% to below 1%. Benzene is a particularly nasty carcinogen (causes cancer). The next step is to reduce sulphur in diesel below 10 ppm (in Europe diesel fuels with sulphur lower than 3ppm is on sale). Of course, the real, original, “old petrol”, better known as white gasoline, only had an octane rating around 30 - 50. |
