Re: Lucas Oil stuff

i constantly use lucas oil treatment in my 72 and my 92 chevy. i also used in cat engine when i was a owner/operator. it boost the oil pressure a little and it also helps on cold start ups.

Re: Lucas Oil stuff

Cool... anybody else?

Do you fill up oil as normal and then add that? A whole bottle?

Re: Lucas Oil stuff

I always add a quart of Lucas, to everything except my BMW (which uses synthetic) I do one less quart of oil and replace it with Lucas.

Re: Lucas Oil stuff

i wouldnt use it on a new engine. lucas actually thickens the oil like molasses and makes a slick film on everything and that film collects crap and doesnt allow your oil to clean like it should.

Re: Lucas Oil stuff

In this area, the parts houses can't hardly keep it in. I have to order in extra between trucks because I run out continually. Great product. Big City, they have a Synthetic version out for Syn oil users. - Jerry

Re: Lucas Oil stuff

Sal-give it a break in period.....I have always suggested 5000-6000 miles for a proper break-in to all my customers before adding any additives to oil. See if others agree. Even when I run synthetic, I break in with regular oil, 1000 miles first change, 3000 second change, then I go to synthetic at 5000 miles. I had 260,000 miles on a 91 suburban bought new before a hail storm totaled the truck, and 130,000 currently on my 99 s10 bought with 12,000 miles and immediately switched to synthetic the day after I bought it. Not an engine problem(oil related) with either. My 65 c30 when done will be syn as well. Jerry

Re: Lucas Oil stuff

10w40 or 15w50 either one is great for a V8 and the viscosity does not change with temperature, so cold weather startups are NOT a concern.
