Break-In Oil ????????? Dealer???????

[CampMan]

The engine oil in a new Kubota Tractor:

Is it; A) A special break-in oil that needs to remain in the
tractor for its first 50 hours.

B) A regular type oil that could be charged at the
first 25 hours then again at 50 total hours, just to
make the engine super happy.

Dealers are confused, they have said both.
BREAK-IN OIL BIG QUESTION - DEALERS NOT SURE

To my understanding the oil itself is not truely different. The term brake in oil is used to describe the fact that the engine is in the brake in process. It is usually recomended to leave the original oil in for the first regular change interval to avoid the contamination of any new oil you add. Durring the brake in process the rings,bearings,lifters,pushrods,rockers,etc will seat in and you will have some wear from this. By the first oil change this wear should be minimul and wont contaminate the new oil to the same degree. I dont believe you would hurt anything by changing it early, you may want to change it early again the next time too. Just my opinion from what I've learned, see what the other guys say as well.

HGN is correct, the break in oil is no different from the oil you will put back in it.
I don't know if you will make your engine super happy or not by changing it sooner not unless your enviroment is really dusty and your working the snot out of it...then it will help.

Well the real answer is yes and no.

No the oil itself is not special other than its' not a synthetic.

Yes its' breakin oil, sort of, because it has the assembly lube or lubes mixed in with it.

If you want to change it at 25 hrs just don't use a synthetic or put in additives.

Once your at the 50 hours mark, can you then change to a synthetic oil?

I installed Amsoil at 000.30 hours.(3/10 of an hour)

I install synthetic ASAP when I get whatever auto.. No problems to date, in any auto. /forums/images/graemlins/grin.gif

Not sure that this would cause any problems with todays engines. My understanding is that with a new engine it needs to "lap in" so to speak and if you use synthetic from the start it will not let it do so because it is more slippery. I prefer to use dino oil anyway, dont see the benefit of the additional cost. But this is stepping away from the orriginal post.

 

[gsxr1100]

the rings will set but it will take longer and have higher oil consumption; which I will gladly take over more wear.

For me this process has worked on my autos since 1991.

 

[odleefs]

Isn't taking longer to break in a good thing?!?

I agree, increased oil consumption is a small price to pay...change to synth at first oil change.

If your engine was made in the 1960's this would be true. With better manufacturing techniques and better understanding of metallurgy, engines are being designed better and to tighter tolerances today. The old days of break in oil are long gone. Today many engines are factory filled with synthetic oil and even the weights of the oil has changed. The new Mercedes are being shipped with Mobil 1 0W-40 weight oil and the change intervals have also been greatly increased. Oils, engines, manufacturing techniques, etc all change faster than we as humans allow for change, hence the old theories of break in oil persist. Personally, I feel that the engine on my Kubota will last as long as any other even if I don't do oil analysis or use Amsoil synthetic. Changing oil and filters as recommended will be enough to keep my Kubota humming for many years to come. Do what makes you happy, but stick to the manufacturers recommendations and you will have no problems as a result of lubrication. If your engine is prone to throwing a connecting rod, then it will do it whether you use synthetic or dino oil. You can't alter the performance of a defective part by using one oil over another. Oil analysis can't tell you that a part has a hair line casting crack and is going to self destruct at 300 hours. Only a we gee board or crystal ball can give you this information in advance. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif
