Kinda off topic for us but lots of knowledgeable folks here:

If gas is put in diesel but not at a high enough concentration to ignite, will it still smell like gas or does the "new" diesel smell like gas? Never really put my nose to it enough to know, but I thought diesel still smells like diesel??

 

It'll have a new smell known as giesal.

Sorry....I don't have a real answer as I've never smelled a blend of the two.

 

This definitely smells like gas but it won't ignite at all.

 

are you able to mix some gas and diesel and see if it will ignite?

 

even a small amount will make it smell like gas.

 

I just put half a gallon of diesel in my lawn mower the other day because it smelt like gas.
So this is a pretty good topic.

 

That's strange because we've had this come up before (with red fuel). We have a machine here at work that refuses to start and, of course, the last thing checked was the fuel, but the machine only has 50 hours on the clock. Even my newbie parts guy thought it was gasoline and not diesel.

 

Hmmm--On mine--I could tell only after I poured some out on the ground and let it set for a few days--that oily diesel smell came back.

 

Will it ignite at all with a match? A real strong diesel concentration is hard to get to light with just one match. More gas and it will light right off.

 

I used a butane lighter and no, it wouldn't light at all.

 

Probably too much oil to gas ratio and is why the engine will not light off/start.
I assume we are talking about a gas engine with diesel or is it a diesel engine with gas in the diesel?

 

You can put a cigarette out in diesel fuel.

 

diesel engine with gas (maybe) in the diesel. Cranks and cranks, no smoke then starts labor knocking and smoking like a freight train but will not start.

 

Ok maybe I should ask now what I should have asked first. What type engine?
Perkins;Cummings;Yanmar;toyota???? 2cyl/4 cyl or bigger??

 

4 cylinder Fiat Tier 4a diesel. Approx 3.9L.

Brand new engine with 0 hours that replaced a "dusted" engine with 50 hours. Even has a new PCM.
