Have a v8 .troopy and towing a jayco outback eagle. cant come to grasps with the fuel consumption let alone the oil usage. Has anyone been towing with one of these and been using oil as well as a lot of diesel. Have heard on previous forums something about this but cant find them. Just as a comparison would like to hear

You would need to be more specific, like how much fuel and how much oil.? I haven't heard anything about these new V8's using plenty of both. Off course towing will lead to increased fuel consumption, oil..? Should only be minimal.

I have had a V8 Turbo ute now for 3 years. I have done 65,000km in the bush towing trailers most of the time. While I have been using more fuel than I would like (averaging 16.5lt/100km ) it has not used a drop of oil between services. I have heard that some people were having oil usage problems but I have not. I have driven the ute hard since day one and have not had a problem with it,

Hi,
At work we have two troopies. Both use oil as they need topping off every so often.
They get turned over at 40kms so no idea if they settle down.
In fact the oil light came on in one I was taking for service the other day.
Regards Alan.

westozal,

Oil usage in these engines is a well know issue. Contact your nearest Toyota dealer and they will assist. There have been some 'fixes' mentioned.

The LCOOL forum is the place to gain further information.

Cheers,

Mark

I own a 76 Series V8 diesel and have just towed a 20 ft van from WA to Cairns, it has just turned over 30,000 km. It used about 500ml of oil over the trip of 7,500 km, I think this is acceptable. I was well aware of the oil consumption problem with this engine but as a diesel mechanic I believed it was just a matter of glazing, eg, not enough hard work on initial run in. I made sure I worked the engine by towing the 3 ton van and the engine stopped oil usage by about 15,000km. Fuel consumption average is 11.3 L/100km general driving, with roof rack, 13.4 L/100km on off road tracks and 16.4 L/100km towing the van around 90 Kph. The oil I use is Penrite HPR Diesel 5. While on the subject of oil Penrite have an oil Syn 5, that can be used in gearbox, transfer box and diffs and is recomended for heavy duty work, I will be changing to this oil when the 40,000 service is due. Leaving Cairns for the Cape tomorrow, love the vehicle.

Kevin,
that is excellent fuel consumption.

Have a good one.

Hello Kevin,

I'm interested to know if once a diesel is not run in correctly is their any fix or will the engine always not be at it's best other than rebuilding etc?

Regards,
Dave

Davo,,
Once an engine is glazed it can be a problem to rectify. The only thing you can do is work it hard and hope for the best, it may solve the problem depending how bad it is. I believe that regardless of all of Toyota's fixes this is the base problem with this engine. All diesels need to be worked on run in or you risk oil burn down the track, especially an engine of this capacity in a vehicle of this size, this is my experience over many years in the trade. Take a new V8 tray top with a tradie's tools on the back running from job to job, stop start etc, it stands to reason what will happen. Oil quality and grade is also important, there are four basic things an engine needs for a long and rewarding life, CLEAN oil, air, fuel and coolant.

Mark, we have about 30 V8's at work and around half of them use oil.

Some stopped using oil after a period of time and some didn't.

Can't help you with diesel usage towing, as a bench mark my Troopie with a 6.5l chev diesel and towing a 17foot 6 poptop uses an average of between 17 and 17.5l/hundred.

Mark,
if you pull that right foot back when you accelerate, then sit around 90kph I believe your fuel will improve considerably. Oil!!! I don't know how much you are using, around .5l per 5000k is quite normal for a diesel. The old cruiser 1HZ diesels wouldn't use oil unless you put a pick through the sump.

Hi Mark

I have a V8 ute and at around the 15000k point it did start to use excessive oil. I mean 1.3litre between services. Toyota did a monitor on it and then decided this was an issue. The have a known warranty issue with the seal on the scavenging pump in the sump that only affects some V8s. The replaced the seal on mine with the new double lipped (?? I think something like that) - no more oil problems.

What I mean is no more excessive oil use. It did still use maybe up to 300ml between services until it reached 50000k and now it doesn't use any at all. I was told that it takes about 50k to properly seat the rings in on these new ones as they are so hard.

Fuel consumption depends a lot on your right foot. Being a V8 with lots of power it is easy to push down. Once you go over the 100 to 110k point fuel consumption increases dramatically.

Fuel can be affected if you get a noisy injector as well. I had one at about 23000k point. Sound like a little china man banging a hammer inside my motor. Really loud beyond just a tappet noise. Fuel consumption went about 20/100. Toyota replaced the injector on warranty and all was back to normal.

The only other thing I experienced was the large turning circle. I adjusted the steering limiters by one turn and now it is great. Be aware turning on tight corners especially in 4x4 can damage your front ball joint.

Interesting you say about injector noise. Bought fuel at Tomby Bay on Eyre Peninsula a few days ago an thought by the sound of things when pulled into Louth Bay that avo something had gone terribly wrong with the valves or injectors the motor was noisy and rattly like it had lost timing but in morning was fine who knows.

I have a 200 series V8 and it uses 1 litre of oil every 1800k when towing. The motor has done 55000k, most of it towing and is still drinking oil.

Toyota changed the scavenging pump and it did not make any difference.

hi mark c
it is healthy for any diesel to use a small amount of oil between service periodas some have advsed of there experiences

but not an excessive amount like is spoken off
one thing that will make a diesel use oil is a dirty or partly blocked aircleaner

check this as no one has made a mention of this so far

with all the diesels i have run in they have taken 20-40th km's to settle down and like mentioned they need a load behind them to wear them in
running empty around town is'nt the best scenario for the long term
cheers

Toyota is aware of this oil use and if you ask them they will conduct a test where they check the oil every 1000km. Than if necessary will do the mods to rectify.
I have 40000k up on a ute and tow a Bushtracker Van around including off road . We are averaging around 17lts /100km.

My trayback has a long term average of 12.34 litres per 100 k. Lowest reading 11.06 and highest 15.24. Now done just over 35,000 k. If I use a light foot and am lightly loaded I get under 12. Don't use it for towing. I have not experienced an oil use problem.

I do give it a fairly fast run up the Moonbis a few times a week. That should help keep those rings seated. :)

From what I can tell they use a little less fuel then the Patrol and use a similar amount to the turbo 4s. Perhaps they use a little less than many of the turbo 4s when pulling a big load.

I am very pleased with the fuel consumption figure of mine.

Hey Flynnie I know the moonbies well. Mine when not towing does about the same fuel as yours. Towing seems to be the problem but will continue on and see what happens thanks
