Diesel Driving Style

[gorilla]

Hey Guys,

I was just wondering how you drive your diesels? rev wise.
I drive basically between 1500 and 2000rpm. Don't ever go over 2500rpm.
Offroad is a different story anything goes.
I have a non turbo sd33 patrol.
I am I pussy? it just seems to be where i get the most out of the engine.

[HotFourOk]

In my Rocky 2.8TD i sit between 1500-2500rpm.

If i really am fuel misering, i go between 1500-2000rpm.

If i need to get up to speed quicker it may see 3000rpm.. but no more coz it runs out of puff..

[gorilla]

mmm... 2500rpm!

wish i had some forced induction!

[LuxyBoy]

Keep mine under 3500rpm but i don't heavily gas it; mostly
I watch my EGTs to make sure she is not being overfueld; otherwise i am just forcing dollars out the rear with no gain

[plowy]

my bro would not go over 3000 rpm in his 2.8 hilux
when i got it it would hit 3500 every gear change , id give it back and he would go for a run n ask me what i did to it as it went way better than before i drove it.

[460cixy]

there all hispeed diesels its not like your driveing a huge perkins with a 500 rpm rev limmit just giveit to her ya doing more harm then good by not varying engine speeds and loads

[known 2]

seems all deisels have that same rev range and it gets smaller the biger the engine i rev my 4.2 between 1200rpm and 3500 any higher and it revs with no go.
as for the trucks i drive with motors rangine from 4l 4cyl they rev freely to 4500rpm and still have power, to the largest 12l v8 wich only have power between 1000-2500 rev them much higher and it's redlining

Firewall in every gear!!!!!!!! Well it is 2.4 lux!!!!

well you cant over rev it and the hilux couldent pull the forskin off a jew anyways so you might as well ring its neck

[mac1cruz]

I have a 75 series ute 4.2 1hz mostly drive it between 1500 and 2200 when i sit on $1.10 it revs at 2200rpm...
Also depends what cd iam listening too i have taken it to 4000rpm but that was when i first got it and my previous car was a very fast falcon ute but after 3yrs of owning the cruiser i now know how too drive a diesel properly theres no point in reving the shit out of it....

But if someone is up my arse i put my foot down hard so they get covered in black smoke....MY BAD

[RockyF75]

1500 - 2500 regular daily driving. Cruise on 2grand for best mileage. Take it close to 3000 if i'm trying ti get infront of sum1

Offroad i've taken it to 3500 on very few occasions. One insane muddy hill where it keep dying near the crest , and once at stocko going up a mongrel of a dune, think it went to about 3700 then
this is a lil NA 2.8

[jav]

no idea what revs , but when it won't go any faster change gears, every diesel i've owned.

[Hoppy11]

2.7 Navara, bout 3000 most of the time, gotta get that thing moving eh

HJ75:

I try to rev to 3000rpm just about every gear change and try not to cruise much below 2000rpm. Now and again i'll have a squirt to 3500. In 5th it sits just over 100km/h @ 2100rpm. If i let it lug around town for too long it starts to drive like a pig.

EDIT: Turns out i'm full of shit. I change around 2500-2750rpm most gears, and generally sit at around 1750rpm when 'cruising' around town. On the highway it still sits on 100km'h @ ~2000rpm. In saying that, 3000rpm certainly isn't rare. When the red mist has decended i've hit 3750+rpm (that's pretty well redline)

[tweak'e]

toyota 2.8 normall 2000-3000. (3200 rpm @ 100km/h in 5th gear) 4000rpm when required.

nissan navarra ZD30 3 litre turbo, 2000-3000 most of the time...but unlike the unlike the toyota it seems to love going to 4000. it seems to be more car like than a diesel.

Hey Guys,

on or off . seems thats the only 2 choices i had when it was running

Just curious. Why does it start to drive like a pig if you let it lug around.

[justinC]

I've only got up to 3200 rpm, so lugging is the order of the day...Lucky my peak torque is about 2000......

Supposedly it's because the bores glaze up and compression drops. You might notice that after driving around town for a while (i.e. weeks), a blast down the highway will have your diesel feeling like it's freed up and has a bit more go (because you've been running at high revs + load). I'm not certain that what i experience is due to glazing, but i definately notice i drop in motivation if i don't work it for a while.

My engine seems to make 'good' power and torque all the way up to ~3200rpm.

BTW it's only around 8000km old - i'm just training it

[rampagingturtle]

like i stole it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[j-top paj]

my max torque is at 2000, so i dont need to rev it much, although i have reved it to nearly 5000 a few times on the highway when im in a bit of a hurry.
but around town i usually use it between 2000-3000.
thats with 5.29s

[vanzbrown]

My 4.0litre 60series likes to sit around 2000rpm. If i want to get up to 100kms and hour, its more like 2200 - 2500. Gud fuel economy on about 2000revs, (about 85kmph) and more and it likes to guzzle. I only run 33's.

Around town its like 1500rpm.

The only time it gets above 3000 is low first on a steep hill climb.

Gotta love diesels though..

I have been wondering about the rev range to, my tdi disco does most things in the 2000- 2500 range with occasional 3000 rpm when taking off uphill, 2250 @100kph.

[crunch]

I think the best way to get the most economy out of a diesel is to get it up to speed as quick as possible, then keep it in the highest gear practical. Allowing a car to struggle (ie 5th up a hill) will end up using more fuel, so back change, then again, put it in the highest gear practical after the hill.

[Toli]

It seems that a lot of trucks here manage to sit on 100 km/h at between 2000 rpm and 2400. I sit on about 2700 -2800 rpm at 100 km/h. It is an 80 series TD 92 model. when I test drove an auto it was about 2400rpm at 100 km/h any one else getting the same for a manual 80 series?

As for back on topic, I drive with changes between 1800 rpm and 2500, I also let it rev to about 3000 maybe a bit more when up hill

[HotFourOk]

I run a touch larger tyres, but i sit on around 3000 @ 100km/h...

I just got a GPS, so I'll go and see exactly

110km/h seems like its revving its tits off... I have 31" with stock 3.36 ratios.. I would LOVE to sit on 2000rpm on the freeway.. would be heaven
At 110km/h it loves to suck the juice

[MQSWBUTE]

my tacho dont work i drive mine hard for 1st n 2nd gear but after 3rd i go right into 5th cant really tell u about revs

[+dj_hansen+]

After my pump was rebuilt, was told not to be scared to change gears or charge up hills at 3.7k (hilux 2.4 - 250 thou) however normally change around 3,000 and it see's the odd 3.5k offroad/ or over taking. Sitting at 100 km/hr on factory road grippers its bout 2.8k, on 31 mt/rs its a touch lower, not really noticable. Also gradully increase pedal pressure as acceleration increases.

Dont use a drop of oil between changes (penrite HPR 15), and return about 10l/100km (on BP diesel with chemtech injector cleaner each tank).

Note: people trying to lug up hill in 5th gear, foot flat to the floor and anything lower than 2.5k in a hilux, your running a high risk of blowing 5th gear as it cant take that kind of torque loading.

[The Rocky]

between 3000 & 4000
