It depends upon whether the spark ignition engine is carbureted or fuel injected. It also depends on the ratio diesel:gasoline. If more than a few percent diesel in a carbureted engine it won't run or will run very poorly at best. In a cylinder injected engine it will run well at moderate temperatures up to at least a 1:1 ratio. At ambient temperatures as low as -15 deg. F. engines in good condition will start and run acceptably with up to a 40:60 ratio. Due to the higher specific heat of diesel (energy content of diesel per unit is higher than gasoline) the fuel economy is improved, so long as combustion remains stable. I normally fuel my direct cylinder injected, spark ignition engine with a blended diesel gasoline mixture of between 30:70 and 40:60. My experience using a blend in this range has been an increase in miles per gallon in the range of 10-20% over straight gasoline. If the improvement were due only to the difference in specific heat, then the increase should be only slightly over 10%.
If you accidentally put diesel in a carbureted engine, siphon out as much as you can and fill it with gasoline. You may need to use starting fluid to get it running again. Once you get it started it will smoke until you get all of that initial diesel fuel burned out. If you're down to less than 10% diesel fuel mixed in with the gasoline, it should run OK.

I have used 1oz.of diesel per gallon of gas for years without any problems and to my surprise it cleans the upper cylinder head and plugs really good.
less engine noise and also feels more powerful , I have to push the gas pedal less to reach desire speed.
keep in mind the diesel has a higher flash point than gas ,which means it burns slower and more heat is needed to ignite, that is why diesels are 14:1 to 22:1 compression ratio ,diesel has more hydrocarbons =C12 H23, Gas=C2 H8 I have
also used 30:70 mixture with full-timing advanced 15 BTDC on 4 cyl no engine knocking no smoke just power (advanced timing creates static pressure) heat to help ignite the mixture . on 10:5 compression ratio like VOLVOLs or BMWs this 30:70 should be no problem and great fuel economy .
The fuel savings come from the torque and efficiency not the ECU ,because less
pushing of the gas pedal is needed for some situations, keep in mind the ECU will always try to maintain 14.7:1 ratio in closed loop operation am sure one
could run an engine @ 17:1 fuel ratio (lean) with a really good spark like MSD and no resistor plugs .Do not try this if you are not experience.
Diesel engines run on diesel fuel. Gasoline will destroy a diesel engine.
Gasoline engines cannot run on diesel. Only a diesel engine can run diesel. And a diesel engine cannot run on gasoline.
only if it has a diesel engine. A gasoline engine will not run properly on diesel fuel.
You will destroy a diesel engine if you run gasoline in it. Do not even start the engine. You will have to drain the fuel tank, and all fuel lines.
You cannot burn diesel fuel in a gasoline engine period. A gasoline engine will not run on diesel. So legality is a mute point. A gasoline engine and diesel engine are totally different in design and the way fuel is burned. The fuels are not interchangeable.
Flex fuel does not mean you can use diesel. It means the engine can run on pure gasoline or on E85 gasoline. If you put diesel in this vehicle it simply will not run. Diesel can only be used in a diesel engine.
In a gasoline engine, it is a fuel-air mixture that is drawn in during the intake stroke, unless the engine is fuel injected. In a fuel injected or a diesel engine, it is air, because the fuel (gasoline or diesel) is injected at the "last moment" before ignition.
No. A petrol or gasoline engine will not run on diesel fuel.
If the engine is a diesel use diesel fuel. If the engine is a gasoline engine use unleaded gasoline.
It does not have any sort of fuel type sensor, putting gasoline into the fuel tank of a diesel Mercedes will likely destroy the engine.
No, Gasoline or Petrol as it is also known will not fuel a diesel engine, in fact it may suffer permenant damage if you try.
Only if you put diesel in gas tank.
