New Delo 400

[BIGNASTY]

Went to change the oil in our Ford tractor looked at the label on the 55gal drum and the old boss brought me the wrong one its the LE crap. Is there an additive package that will give back the protection of the old Delo 400. Not that big a deal the FIL's 4th gen and his bus use the LE and that was the only drum that was a mistake but just wondering about additive packages.

Thanks
