so 8km per liter is 22.5 mpg uk right? so 18.7 us
I have never gotten under 18mpg us and thats the worse I think I have heard a 3B running. Mine is natural aspirated fuel cranked up I will hold 55mph up our steepest hills. Running our mountains or long freeways pinning the B out is where I get 18mpg us or 22.6uk :edit 21.6 uk
You are comparing a 5.2 liter diesel running 24psi in a vehicle with a unknown weight? I asked what vehicle. To a 3B na with cranked fuel, posting the worst numbers I have heard of for mileage and you are saying yours is SO much better mileage you don't even need to think of burning free oil, and all because its a DI? so vehicle weight don't matter and the fact you run 24psi of boost. btw 24 mpg uk to 30 mpg uk is not a HUGE difference. I bet if I drove like you I would easily get 26 mpg uk.
Anyways lets play that way since nothing else plays a roll.
My wife's om617 gets 25-30 mpg us thats 30-36 mpg uk And guess what, Its a IDI
Just saying guys we have to have all the facts. Do IDI engines if they where the exact same engine have better mileage? sure are they better? thats up to the individual user. Do they get such better mileage you would never have to DREAM of running WVO? psh yeah right.
I think Dougal just likes to argue, I see it a lot on here. The rest of us seem to actually give pros and cons to each and what we like about them and actual good info to the users. I like seeing the torque curves of each ect because I don't own a 13bt. Thats stuff I want to learn.
Not comparing a 4hk1 to the two engines the OP asked about.
ok I'm done, knowing it won't stop here
Not a 4HK1, it's a 4BD1T. Vehicle is 2.3T empty.
If you want to compare your vheicle to mine, then we are comparing an engine with approximately 130kw to an engine with approximately half that. If you have never got less than 18mpg US then I'm guessing you've never towed or used your vehicle offroad.
It's not a very steep hill if a non turbo 3B can pull 55mph up it.
Veggie oil, waste oil etc isn't free fuel. It takes a lot of time and hassle to secure it, process it and modify your vehicle fuel system to burn it. For the $2-3k worth of diesel I burn a year it is not worth it. I would spend a lot more than $2k worth of chargable time.
24-30mpg is a 25% improvement. That is huge.
Sorry I had to make a guess on the engine. I'm not counting wheeling if thats what you mean. Off road in the cascade mountains where I live camping I'll use 3/4 of a tank cruising 1000 ft to 6000 ft going to hunting spots, fishing spots hiking and use having a good ol weekend. 18mpg.
My na 3b will do our hills at 55 elhi, snoqualm pass 18 east. I dono maybe not steep, we live in a mountains state and those are steep hills for my old cars.
Nah your right wvo isn't free. Though I spend easily 5k in diesel (or use to) and I dono, change my filters 2 at 2 bucks each every several hundred gallons. time spent, I just roll by and pump takes maybe 15 mins for 50 gallons? then spend some time at home with it usually when I am brewing my beer, to tinkering on something in the garage.
Nowt free, just incredibly cheep. BTW it is free for me to get, unless you wanna count the pennys it costs to run my pump.
24-30 I agree the 4bd1t is a great engine I would love to have one. Still don't know what you put it in? a VW rabbit?

lol btw I had a idi rabbit that got I got 45 mpg in it only twice it was on of those hills camping weekends. but usually 50-55 mpg US all day long.
It was IDI if I didn't say that.

IDI engines will always be less effecient due to thermal loss via the pre cup. Many people discount that such a small area can transfer so much energy. With more people interested in IDI, machining a fully ceramic coated pre cup and chamber could mitigate the loss considerablly. But no one does that because there are easier gains to be made with DI technology. One of the only advantages IDI engines have is better air/fuel mixing at high rpms, which most diesel people dont care to take atvantage of. I like IDI engines because that is what I own. The issuzu or 13BT or any DI engine with an inline pump is probably the best combinatio of effeciency and reliability.
Problem with idi is alot are prone to crackn heads over di.( as the precombustn chamber causes more heat & most have 21:1 compression = not suited for turbos over a limit ) , di heads are very simple & stronger design turbo versions have compression 16-18.5:1 ratios& on a performance basis are far better ,are heavier & stronger, efficiency is better with idi . New commonrail injection are based off the( di )direct fundamentals & design .
Id have a direct over indirect any day , but they are harder to come by ( 12ht , 13bt , 14bt ,etc ) have to settle with a idi unless find a di LOL
