Most older engines required leaded gasoline due to looser tolerances and lesser quality ring and cylinder materials. The lead being a soft material acted as a buffer between moving parts and protected metal parts in the engine. Modern engines have very tight tolerances, better quality metal alloys, better oil control, and use higher quality lubricants thus do not need this added protection. Leaded gasoline also emits more harmful gasses into the atmosphere (bunny huggers rejoice!).
leaded fuel is economic compared to unleaded because more distance is covered with leaded than unleaded
Yes because unleaded produces less carbon dioxide and other greenhouse gases than leaded petrol. it leads to a reduction in greenhouse gases and acid rain.
no it does about the same they just give it a fancy name
Since leaded fuel is no longer readily available at most all gas stations, you may have to use an additive. Proper leaded fuel is a little bit better for your engine than non-leaded additives, but hard to get and quite expensive. An additive like Tetraboost adds the lead to unleaded gasoline with lead-scavengers. All vehicles sold in the US from 1971 on are made to run on unleaded gasoline, so there is no need for an additive in your 78 unless you have an older unconverted engine in it. It should run fine on very low octane fuel.
cost of refining the crude oil ofcourse... In the UK diesel is more expensive than normal unleaded petrol.
2.4 petrol is better than 2.2 TD in my opinion.. I just replaced my 2.3TD with a petrol.. 2.4 petrol is better than 2.2 TD in my opinion.. I just replaced my 2.2TD with a petrol..
It burns cleaner than leaded fuel so there is less polution.
No, it is not better it is just another type fuel.
Unless your owners manual says that you must use super unleaded gas, you should just use regular unleaded. Otherwise you are just wasting your money and possibly harming your engine. super unleaded petrol has a higher octain rate than unleaded. check your owners manual for the optimal rate you should be using for the engine.
advantages:it is cheaper than unleaded fueldisadvantages:it damages the mental health of childrenit is harmful for catalytic converter in the car which is very expensive and important for keeping the environment clean.
Higher Octane levels in the higher grades of gas. All gas should be unleaded now.
Yes they arent good cars at all as a matter of fact they are way worse than our cars.
