oil burner intermittent failure to light

Mechanicalhacker is correct on the dye in the untaxed fuel.  Same here in Canada.  Brent@CanBC

Red dye is added to Disel for use as #2 oil. This was done because fuel oil #2 was cheaper than Disel and truckers were using it to save money. If the DOT inspected the trucks and there was no "Red Dye" they knew the truckers were avoiding paying additonal tax.

I meant to leave "No" out. Sr. Moment lmao

It's the other way around... Diesel fuel has no red dye; red dye is added to non-motor fuel, which is cheaper because highway tax isn't added.  If the DOT sees red fuel they know no tax has been paid.
