Diesel testing.

[Johnp33]

Before you spend your money on a testing lab ask them what they will tell you, many labs will not give a lot of information on the fuel. You may want to talk to the company that sold you the fuel, and get their opinion and a heads up on the testing.
I would get a few glass bottles and get a good quantity of fuel.
The printout about diesel fuel was printed in 2000, it is a bit out of date but all pertinent, except for the sulphur content and the addition of Bio fuel as a cetain booster and lubricant. 2% bio added to fuel was the very best above any miracle aditive in a bottle.

Just trying to help someone in a difficult situation. I'm sure that there is more good info out there.

It would be good to see if this tractor/engine combintion has similar problems that might be attributable an engine QC issue rather than gas/fuel contamination. If the OP doesn't find gas in his diesel, the Deere position begins to look less likely. I'm really surprised the injector pump and injectors aren' showing signs of distress as I would have expected the effects of gas/diesel contamination (poor lubricity) to show up there first. Could be his use of a diesel additive masked that, however.

Thanks for the info Jerry. I read something simular on Cheverons site about quality of fuels.

The injector pump and injectors were tested before they tore down the motor, and they were both fine. I filled my sample bottle tonight, and will mail it tomorrow. Its a cheaper test, but hopfully it will give some insite to what happend.

Please keep us informed about howthis plays out.

You said the valve seats were "pitted". Which valves, intake or exhaust?
