Lucas Oil Add.

[coldblooded01]

i have allways use lucas oil add. on all of my motors "all Gas" and have been able to get 250 000 on a 94 f150 and my father has used it for a very long time and swears by it. is it safe/recommended to use it in these new diesle motors..

no. a gas engine or heck just about any other motor it may work well in. on a psd they use a heui injector. basically the oip is pressured to a minimum of 500psi to fire a injector and can get above 4000psi. yes 4000psi not a typo. additives will make the oil foam. do a search on lucas oil additive and foaming and you will probably not use it even on a gas engine

Do not use lucas oil additive in a powerstroke diesel. Hell it even says that right on the lucas bottle

Just perform regular oil changes and you will be fine without any additives. There are some things you can do like add a Oil By-pass system, switch to 5w-40 Full Synthetic...but I wouldn't go with any additives. As far as Lucas fuel additives, my 6.0 hated it...it does like Standayne Performance additive...Cetane booster and a little lubricity. I'm getting ready to try FPPF Lubricity formula.
