Lucas products

If your engine is not consuming more than 2/3 gallon between service intervals, I wouldn't use it. Lucas lowers your TBN in your oil and that's not a good thing. You are using one of the best, if not the best conventional oil with your delvac in my opinion. It has all the additives and properties it needs to begin with, so why dilute it. I used to be a big believer in rotella until 2007 when the cj4 plus stipulation came out and shell had to jump through their rear to meet it. After some research, found out delvac had already met that criteria 3 to 4 years earlier. A lot of my customers who stayed with rotella during the changeover went to consuming more oil between changes. So we swapped over to delvac and problems went away. Have no qualms with rotella t-6 synthetic, it has proven to be an excellent oil, especially if you're running an OPS or some other extended interval filtration system.

 

Lucas Oil Stabilizer=Snake Oil

 

is it any good? not sure but I ran a gallon in an old 2000 kw for 10 yrs at 1 million and 68 thousand miles when I decided to overhaul it the cat shop called and asked if I really wanted to. still had cross hatch marks on liners and bearings looked great. never had an oil related failure. do I still use it? no. I could not justify the cost jump of ten dollars over night when they did that a few years back.

 

The engineers that designed the motor made it so the oil flows in a certain way to cool and lubricate the parts and pieces. If you add a thickener you change out the flow pattern, for what reason?
When I was working, a gear man, pulled an 18 speed for a major failure, he called me over to look at it, he had the cover off. it was a mess. the eaton rep came over, he looked at it, and turned the input shaft, and said LUCAS no warrenty.
As far as their injector cleaner, Bio is a great cleaner, and you will have a hard problem not using it, also In all my years when a customer came in with a fuel problem, not once did the customer tell me he used an aditive.
I got out of the business in 2007, and was a great believer in Shell, Delvac is a little harder to get but will seriously think on that recommendation.
Just a thought!
If you want the best thing you can do to your fuel system run a Davco fuel filter, and a spinner oil filter. That does a great job.

 

Over 1M miles on reman 6TS Cat, never used Lucas products.

 

well I don't mind telling the truth. used the fuel treatment in the past. filled my davco up with, the rest in the tanks. definite improvement in starting & in m.p.g. I used 1 gal oil treatment at every oil change when I first got my truck went 11 years over 1.32 million miles & when had inframe done shop said I could go to 2 million easy & said what ever I was doing just keep doing it. maybe the lucas not not helped at all, but I did not think it hurt it. though I always changed my oil at 10,000. so that may had more to do with the good luck. I have used, delvac, rotella, delo I use what ever is on sale. right now it rotella at $9.00 a gal total price, tax eviro fee, e.t.c. I just never believed the statements that the engine mfr & the oil mfr made these things to last, & to benefit the consumer. their money is not in things that last.

 

The only thing that they sell that is worth spending money on is their grease, the green stuff. It doesn't "fling" out of slip yokes and u-joints like most other greases that I have used, keeps water out much better also.

 

I have said before if a fuel treatment gives you add MPG then it must be giving you extra power from the same throttle position, that is easy to prove especially with an electronic engine, put it on the dyno and run it for 10 minutes at say 70% throttle position, pore in the aditive it should speed up, in say 10 minutes it should speed up if not it is doing nothing. I ran trucks on the dyno, we tried it with most every aditive out there not one did a thing.
I was taught, and it has been proven to me that the cheapest overhaul you will not need is an oil change. The shorter the interval the longer they last. I live in BC we have mountains with long steep hills, we had lots of trucks that went well over a million with regular oil changes at 12,000 miles, we had lots of trucks that did not get close to a million and they changed it at 20,000.
