Oil usage in 200 series T/D - when does it slow down

G'day pling,
You have to realise modern engines run hotter and therefore cylinders have to be lubricated and on every firing stroke any oil on the cylinder wall is burnt off and is replaced on the next stroke. If no oil engine would soon seize.

Yes I am using the same amount and it has not slowed up I now have 40000Km up. Last week when I talked to local dealer he advised they do not have a fix as yet. When I questioned him on the vacum pump I had herd about as a fix he advised that was not correct. I checked with an other dealer who I trust, they advised that the vacum pump had worked on some but not all and yes they do not have a fix but the new ones seem to not have the problem. When I asked are Toyota going to cover under an extended warranty , he went very quite. I don't believe they are as good as the 100 series they just have a lot more power.I am starting to here about problems with tail shaft's, dust not good for car as expansive as they are. This is my third but think next time I will do a little more research before just going to Toyota.
All the best

"Strongish rumour

The pistons do not have an oil bypass valve to properly lubricate/cool the piston. This means the piston runs hotter (& hence the engine failures) but because they run hotter the external cooling causes the oil to get much hotter during the cooling process producing more fumes. The oil is able to cool down alright its just the increase in temperature of the oil whilst it is actually cooling the piston

More fumes means more gas to separate & hence higher consumption.

Solution will be a recall to replace pistons, particularly seeing there have been some engine failures as opposed to just oil usage. The engine failures may be related to bio diesel only in that if the ethanol is not fully separated from the bio diesel during manufacture then the fuel will burn hotter than normal, thus causing a problem only because of a design fault in the engine itself

Toyota may have considered not doing a recall because oil consumption was not seen as a big problem, but with engine failures it becomes necessary or at least prudent

Single turbo V8s are effected in the same way.

As I say its only a rumour so far"

"After complaining to Qld fair trading about high oil consumption I received a letter from Toyota confirming that my vehicle is out of line with there specification of 1L/8000kms. The engine will require several internal changes and checking of the ancillary lubrication system. They will rectify my engine in the shortest possible time after parts arrive in Australia.

Went to the Dealers to book the car in and asked what internal parts need to be changed. After talking to Toyota the Dealer said they will change a full set of rings and pistons. Waiting on parts from Japan."



The only confusing thing regarding your vehicle is that from August 2008, all the pistons and rings were supposed to have been updated.

As a 200 Series (Nov 2007) owner I'm watching closely.

Mate got one for his work.
Heard about the oil useage and bedding in problem, of the rings
He just gave it absolute heaps, and it has never used a drop of oil.

Other Tradies in the area have gone gentle on them, and suffered the "bedding in" and oil useage problem.
You go figure it out !

Opps..... Wake up Dopey !

Read the post Bucky LC200 not the Ute..but it is the same motor !

Dosen't matter, but at least in the Ute you have the ability to give them heaps through the gears.

Bag it up and manually select up and down thru the gears, and bed those rings in properly.......Should have no oil useage problems.

Cheers again .

I have a June 2008 TTD @ 46,000kms and it hardly uses any oil - around 10-20mm on the dipstick over 10,000kms. But I drove it like I stole it for the running in and also make sure that every second tank or so I get in nice and warm - such a chore :)

The problem with the 200 V8 is that it has SO much torque that if you drive it gentle you can easily not exceed 2,000rpm on a 1/4 throttle and still be in front of the traffic. But now you start to glaze the cylinders and there goes your oil consumption. Too many people drive the 200 for maximum fuel economy ALL the time when a simple full throttle squirt will fix 90% of peoples problems.

Also, all motors do use some oil, its a simple design fact. The difference is how much oil is used and this depends on the engine design. The 200 has relatively "loose" pistons and if you do short runs and not warm the engine, there has been reports of high oil consumption. This is normal for short runs. Those same vehicles also report virtually no oil use when used on long runs. Check out the threads on LCOOL.ORG and you can read a whole heap about it.

There is heaps of information about the oil use of the 200 V8TTD on the web in various places, some accurate, some conflicting, most inaccurate and some downright wrong.

The common theme is that most do not have an issue, some have a small issue and very few have a big issue. Unfortunatly yours does seem to be in the big issue catagory and should be on the Toyota oil watch list :(

Guys not a 200, but we had and Isuzu 250 truck that was a bad oil burner. Suddenly stopped at 100000ks after a hard quick run.
Cheers Pete

Thanks to all.

I do drive for economy and that seems to not help the situation.

Most of my km's are on the Hume Highway and are a minimum of 200 ks from start to finish. (Home to farm and return)

Will try the advice, "drive it like it is stolen".

Reminds of the old saying, If it has four wheels or a dress, it will cost money.

Thanks again.
