How to empty the tank on a Yaris! - Toyota Yaris Forums

Yaris Hilton · 07-28-2009, 10:26 PM

Up to 10% gas in diesel fuel has been recommended in winter to keep wax from precipitating and clogging the fuel filter. That came from the owner's manual of my Dad's 1983 Diesel Chevette (Isuzu powered) as an alternative for winter fueling when the recommended #1 Diesel fuel (which is ordinary kerosene) was unavailable.

Gasoline will effectively decrease the cetane number of your fuel and make the engine knock more. (Diesel knocking is a consequence of delayed ignition after the fuel's vaporized and mixed. High octane doesn't help that, it makes it worse.) That, and reduced lubricity of the fuel in the pump and injectors are what limit the use of gasoline in most Diesels. You might be interested to know, though, that gasoline is the original fuel that Dr. Diesel used in his first test engines in the 1890s.

It's not hard to stick a hose down in the tank and pump or siphon the fuel out.

Until you come across those with plastic balls and wire mesh blocking the tank inlet.

Have you come across those on a Yaris?

Since you mentioned diesel Chevettes and 19th century engines I just figured we're not being Yaris specific at the moment. Sorry. No, never dropped a Yaris tank, but filler tube is very small and goes nearly straight down with a few other fairly tight bends, so a ball and/or screen might not even be required.

At any rate, I don't think total emptying of the tank is necessary. If it were mine, I'd fill it up to the cap with diesel and drive off with a cautious light foot on the throttle, but I wouldn't think of telling the original poster to try anything like that.

It's all good, I guess? BTW, I don't remember telling the OP anything...I was simply stating that devices probably aren't needed because of the small filler tubing and tight bends on our Yaris.

Well the shop drained the tank and put in 20 liters of diesel for me so all is well I suppose. Got an appointment for next week to get a new windshield.
