Adding BTU to Diesel fuel

[Idle_Chatter]

How much and at what ratio? I'm currently adding Standyne Lubricity. If 2-stroke is close in price I can switch to that. I know 2-stroke will certainly burn well.

I'm still adding FPPF Total Power for cloud point and lubricity. I've been adding FPPF to every drop of fuel I've ever run in this truck, and I'm really concerned about lubricity and cloud point with ULSD (untreated ULSD clouds at +10 F and we've been double-digit below at night here in Idaho). As far as the 2-cycle. It's 100:1 oil, I put a full quart into my 40 gallon in bed aux and 1/2 quart into my 26 gallon OEM tank. (Thats 32 oz/5120 oz in the aux, which is 1:160 and 16 oz in 3328 oz in the OEM, which is 1:208) I didn't want to dose too heavily with the thick oil in subzero temps, although it is snowmobile oil.

Anybody understand the difference in OCTANE rating and CETANE rating?

Or that Diesel fuel has 20% more BTU content by volume than gasoline, and that winterized Diesel fuel still has more BTU content than gasoline?

Why would you want to lower the cetane rating any more by adding gasoline to winter Diesel?

Or dilute the viscosity rating any further?

It's those old wives' tales that gave Diesels such a bad rap.

And, don't get me started on Acetone.....................

I honestly didn't know that Diesel has more BTU than Gasoline. That explains a lot as to why a Diesel is more efficient than a gas engine. I could never quite explain that. The only reason I thought that gas had more was because of EGT's. The EGT's are lower on my truck than in my gas car and the truck is double the weight and double the engine. My street car routinely cruises at above 500-600 degrees EGT while my truck is never that high while cruising. Both are turbo charged and intercooled.

Good Day!

"...Diesel has more BTU than Gasoline. That explains a lot as to why a Diesel is more efficient than a gas engine." ...& a diesel has no throttle plate. Last time I checked, it took hp to produce a vacuum. A gasser is ALWAYS producing vacuum, even at WOT. During most driving conditions, the throttle plate on a gasser is partially closed, refelected by the amount of manifold vacuum produced. Your diesel draws all the air it can, all the time.

The combination of more BTU's in the fuel, & lack of a throttle plate, is most of the reason diesels always achieve better mpg than gassers.

Blessings!

That's a piece of the puzzle I never thought about!

Adding 2 stroke oil to diesel.

Does it matter which brand you use at all? How much to add? I think i read 1/2 quart for 26 gallons...anyone else have anything to say about it?

I dump a Qt. of any thing I can pick up cheap. 10-40, 30wt or 2cycle. every time I top off. But still use Stanadyne blue or Howes all year.If the Motor oil gets to concentrated I can smell it in the exhaust and I skip a dose. The oil is mainly for peace of mind for lubeing the pump. If you want to see what extra BTU's can do for your truck, chuck in some Home Heating oil and boost the cetane. Your truck will love it.

FPPF and CRC are other brands of fuel additives, like Stanadyne. The folks that convinced me to start trying it were sold on the new TCW-3 rated low ash oils. There are synthetics, too, but I wanted something without a lot of additives. I'm currently using Castrol 2T Snowmobile oil that I'm buying at the local Cal Ranch farm store for $2.99 a quart. Quite a few folks are using Wal Mart 2-stroke oil, but I haven't tried that.

Another reason for NOT adding gasoline to diesel would be the 10% ethanol found in most gasoline. Alcohol in diesels is not a good idea.
