Unless you are running a flat tappet motor do not us the additives because some actually do more damage than help. After engine break in go with a good synthetic motor oil. I use Amsoil myself on my fleet. As a testament I have (5) pickups and vans that have over 250,000 miles and one is at 364,000 on original motors. Just my two cents

Here is what's in Lucas additive:

Unless listed all are 'Zero'

Lucas Virgin
TBN - 0.1
Visc - 615.3
FP - 435
Calcium - 3
Magnesium - 1
Phosphorus - 4
Zinc - 2

Bottom line, nothing in an amout of value except thick base stock.
Any 15/40 diesel with a bottle of GM EOS will work very well for break in.

Thanks for posting that Rick...
So using Lucas will actually dilute the ZDDP you all ready have lol Personally I would use Valvoline racing oil, high in moly and ZDDP or use a normal conventional oil with the EOS. Some Diesel oils are good but the formulas are changing constantly so something that was good last month might have very little ZDDP today. Another problem with Diesel oils is they are quite often low on Moly.

In the end I honestly don't know what difference, if any it will make. But since we are nitpicking here you might as well try and find the best oil (on paper anyway)

Yup, the zinc would go down based on that lab analysis. Lots of profit in that bottle.

I know a guy put some Lucas oil stabilizer in a lawn mower and it thew a rod in no time.. He tore the engine down and he found that stuff just make the oil balled up and not lubcating the engine.

Been using Valvoline VR1 racing oil (go to their web site for specs) in my stroker for the last 3 years, with excellent results. Used a bottle of EOS along with the VR1 for the breakin (flat tappet cam). Since then, only VR1, changed @ about 3000 - 4000 miles.

Oils with an SM rating, such as Rotella T and all modern car oils, have only 850 zinc and 800 phosphorous, about 1/3 of what they used to have. This was done to prevent the catalytic converters from being ruined.

Flat tappet engines need at least SL rating (1000/1000) or SG (1250/1200) preferred for break-in and general use.

Ratings are mandated by the feds.
Check the labels for zinc/phos. ratings on all oils.

IMO any SM rated oil needs EOS at every oil change if you have a flat tappet cam.

I have no opinion about Lucas or STP added to engine oil.

Oh ya, and when you do a cam break-in, MIX the additive and the oil BEFORE dumping it in the crankcase. How long do you think it takes for the additive to mix with 5 quarts of oil and get circulated? TOO LONG.

IMO that is why people using EOS for break-in are still killing flat tappet cams.

I know this is kinda WAY out there, but I look carefully at labels and noticed recently that some (Super S) chainsaw bar oil I purchased awhile back was stated as containing "Petroleum Hydrocarbon Lubricants" and "OrganoMetallic Zinc", however it is also stated "not for crankcase use". I wonder though, if 1 qt chainsaw bar oil blended with engine oil would work for a cam/lifters break-in mix? I'm not likely to be the 1st one to try it out, but perhaps others might've pondered this question?
Anyone ever hear of someone attempting this or perhaps using it successfully?
