I was thinking 3,000 miles for the OCI as well. But for the next fill, i was considering maybe a 15w-50 or something similar for the fill? what is it about Lucas that quiets noisy engines... is it simply the viscosity, or is it the stuff in Lucas that makes it cling to every surface and makes it all gooey and stretchy that makes engines quiet?(anyone who has ever poured a bottle of Lucas knows how clingy and sticky this stuff is). because if it is simply the high viscosity that makes Lucas the noisy engine cure, then maybe i'll try a really thick oil instead, no additives. hmm. anyone have any guesses?
I think it is the viscosity, and the fact that it seems to cling to metal with a thick gooey consistency. It sometimes acts like a thick insulation blanket muffling noise. Many wholesale units went out with Lucas Oil Stabilizer in the sump were I worked.
I had a used car manager that decided there was a lot of money in selling high mile trades instead of wholesaling them. He convinced the owner and GM of the Honda Dealership I worked at to try selling these high mile Gems. Something they never did because they felt it would hurt their rep, [they were right too!] I remember a clean Civic ~110,000 miles with a low end knock that was sent to the shop for some work to get it ready for the line. The mechanic called us and said the engine had a knock, do we want to wholesale it or try and quiet it down to sell. Naturally the manager said get it ready for the line as cheaply as possible. In went the Lucas, it worked, for a while. Funny thing was about 2 months later the guy came back complaining he heard a knock just after changing his oil. The used car manager sent the guy packing since his 30 day warranty was up, the customer went to the GM and they ended up cutting him a deal on another car. He was one of the lucky ones. We stopped selling high mile cars................
