Put at least a quart of 2 stroke in every tank if I can...diesel fuel isn't what it used to be. They tooken all the goodies out of it an now its mega super low sulphur clean diesel with biodiesel. The diesel engine was originally designed to run on peanut oil, the only reason fossil fuel became so popular is because of the low cost(back in the day) but now ppl are addicted. Met a guy in salmon arm that runs his 12 valve on French fry oil,,, so I say the more oil the better
Where to start? Our grandchildren will definitely benefit because "diesel fuel isn't what it used to be"
First, the only thing removed is sulfur which is a corrosive in the fuel system and a poison in the air when burned. That's a "goody
The first diesel engine was developed to run on coal dust.
People have been running diesel engines on french fry oil for decades. Restaurants used to give it away until they found out there is a market for it. In the short term just about any combustible liquid can be used as fuel. In the long run, the only result will be shortened engine life.
On a $200 to charity challenge I did a Stanadyne test. A Stanadyne dealer claimed greatly improved mileage and also put up $200. I used a gallon over a 3500 mile route from TX into Saskatchewan and back into Montana. The weather ranged from mild (in the sixties) to being holed up in a motel in BC during a blizzard. About half the miles were towing a loaded enclosed cargo trailer. There was no gain in mileage, actually a slight decline. Stanadyne costs roughly 1 cent per mile, which doesn't sound like much until you do the math and find it comes to over $100 per 10,000 miles of driving. To me, that money is much better spent on beer.
I wish I could pinpoint the 2 cycle oil myth about it's benefits. I doubt it will hurt anything other than a bank account balance. There isn't any way it can improve mileage since it's BTU content is lower than #2. For the price of a qt of oil you can buy a gallon of diesel, so dollar for dollar, the price of driving goes up.
Bottom line, using either or a mixture of both only costs money and gives no gain. The misinformation about fuel lubricity was started by additive manufacturers and has never been authenticated by an independent test facility.
