Donna writes: I would appreciate some assistance…..accidentally put diesel fuel in 2000 Yukon instead of unleaded……what can happen, had the fuel siphoned out and added fuel injector cleaner but truck tried to cut out earlier but runs. PLEASE help!

Donna, I’ll bet that never happens again!

Anyway, the fuel injector rail should have been flushed out also. The oxygen sensor may or may not get damaged, but I think your fuel pump will be ok.

Once all the diesel fuel has run its course and your engine quits smoking you should be all good.

You know Donna, regular unleaded is less expensive than diesel ;-)

Have a great day and drive safe!
