What does your engine manual say?
If the oil consumption is more than to be expected, start planning and saving up for some serious maintenance.

I don't use oil additives. I use NAPA oil and fuel filters with 16qts of Valvoline Premium Blue, 15-40 in my 3208 T/As. I change the oil around 300 hours of running and take oil samples.

However:

I do use fuel additives. A gallon of Lucas when I refuel and at the beginning of winter, I use 8 ounces of BIOBOR JF in each main tank.

Is more better -- NO !!

What I interoperate the OP as asking is this.

he is saying: "I used this additive & it seemed to him that it helped".

Then he is trying to apply & Use the logic that:
---------------" if some is good, then more is better." ----------------

Let me tell you that the resounding answer is: " NO !!".

Additives do not replace oil & are not better than your base oil for lubrication of the internal moving parts of you diesel engine.

They are meant to be used in relatively small quantiles & not to replace 20% of your lubricating oil.

OK - if you want - So you could go to 40 wt. oil & that would be OK as long as your going to use a top quality DIESEL rated oil.

If you insist on using an additive, Use the quantity of Lucas oil treatment you say you used the first time. -- That will probably be OK - maybe.

BUT DO NOT REPLACE 20% of your oil capacity with additive.

Nuff said !

Good luck.

Alfa Mike.

thanks, guys. i put 5 gallons of clean Rotella T4 15W-40 oil and will not use any additives for now and will see how the engine will behave and sound next season because I have some data to compare now. i'm planning to do a few extra maintenance items in the winter so it may help to avoid additives to keep the noise down as well.

The mandates of the Air Police , requiring exhaust gas to be fed into the intake (EGR) is the reason modern oils contain a large dose of additives.

As few of our engines have this feature the old standard CD oil works well, with out the modern detergent package .
Single weight oil does a fine job s very few need the cold starting ability of multi grade.

Old style perhaps , but so are so many of our engines.

I run Detroit Diesels that are one oil change away from 5000 hours. Sine they need special single weight low ash oil, I see no harm in adding an additive when changing the oil. The only harm that could be done was to my wallet.

Not your question but an additive comment:

I did a with/without comparison a few times on the recommended amount of TuffOil into our 5qt sump (Perkins 4-154), added to Rotella diesel oil.

rock solid dependable 500RPM idle without, and 750RPM with. No other changes...

YES. I started using it in a VW Vanagon when the engine started needing oil more often - 100k + on a small 4 banger gas engine. It helped - a lot. Better oil pressure and less oil consumption and so far another 50k on the engine. The engine was a rebuild that is now pushing 20 years old.

Lucas stabilizer IS oil after all.

I was thinking of adding more than 1lt per change also to get the same ratio as the little VW engine. But it costs more and diesel is already 'oil' so I just add the one liter.

I own alot of small 2.7 liter to 15 liter diesel engines . I normally do not go for extra's but i am a firm supporter for lucas. I started mainly because i help a friend on his race cars . He allways use lucas @20% i started using it on my big tractor . It has only one job pull the big air drill pretty much 90-100% engine load 12hr to 40hrs at a time. Using same oil same load ect. Before lucas the last 60 hrs of an oil change i would easly burn up at least a gallon a day of reg oil. Once i started using lucas i would only have to add maybe 1gallon of oil between oil changes.to me the biggest thing it helps with dry starts definitly makes it more sticky... I use it on every thing now even the gaser engines ...i am still firm beliver that most products are snake oil. I definitely am a lucas oil fan

i`ve used an additive called HYPERLUBE for many yrs! in my opinion, it works! it says on the bottle to use 10% in diesels, so i`ve always used 2 qts, in 6 gallons of oil. i usually put about 300 hours a yr on out our single volvo...clyde
