Lucas Oil?

Friend suggested I put lucas in with my oil. Read over the bottle, all the usual miracle oil claims, but I'm curious who on this board has used it. The stuff is incredibly thick...almost like caramel. Doesn't seem like the kind of thing you'd want in an engine. thoughts?

I am using 20W50 Valvoline racing oil with high zinc in it along with Bars Leak rear main seal conditioner. Back in the day... STP oil additive was used religiously by many and it was quite thick. I never used Lucas but I assume its like STP? If it is I wouldn't think it would hurt.

Lucas is good for older cars with larger tolerences and/or wear.

But I wouldn't recommend it for LSx engines or newer engines that recommend light oil.

I change oil in 1 of the NAPA trucks here in town and they have been putting in LUCAS every change sense new. The truck has over 400,000 miles on it now with nothing but normal service.
I've also used their power steering stop leak/conditioner with awesome results. Gets rid of that 'morning sickness' and stickiness found in some racks when it gets cold outside.

Lucas oil stabilizer is a great product and I used it for many years in my Pete until the cost became to expensive. It only takes a small amount for 5 quarts of oil and be sure to add it while the engine is warm and running.

just did the oil with castrol high mileage (love the extra additives BP throws in there) and a bottle of lucas. she seems to run just fine despite the gluelike nature of the stuff.

As long as you add a ZDDP additive you'll be fine. Lucas is not a ZDDP replacement, to my knowledge.

my understanding is the high mileage oil should handle that. the zinc additive is to help the valve seats, correct? Castrol high mileage is loaded with additives for wear resistance and such, which (i assume) would be effective on the valve seats. may be wrong on that front though.

Other side of that is i've struck out finding ZDDP here in town...neither o'reiley or autozone had it, haven't tried pep boys yet, but they never seem to have what i want.
