To CRDi or not To CRDi (This is for a possible mit pick-up purchase)

ibig nyo sir sabihin ay di durable ang CRDi engine? will it conk out after 5 years?

I don't mean it that way sir. Durable din ang mga CRDi engines kaya nga sila ang wave of the future for diesels.

Yun lang at sa dumi ng diesel dito sa atin, hindi malayong magluko ang mga injectors sooner than later due to wear. As far as i know, pricey ang mga ito. And since specialized ang mga components ng CRDi engines, mapapa-casa ka talaga. By normal wear and tear, may mga papalitan nang components ang anumang engine by 80K km, and after reaching 100K km. Mas mahal ang mga components na ito compared sa mga papalitan sa old school diesels. Kaya nga in general, mas mahal ang maintenance ng CRDi vs. old school. That's what i meant for "five years". No offense meant.

sinabi lang ni marcdom na mas matipid in the long run (maintenance) ang Old School diesel, hindi naman niya binanggit na mag-conk out na ito after 5 years. pare-parehas lang ang tibay ng engine basta properly maintained.

sa crdi kasi, computer controlled ang pag-inject ng direktang krudo sa makina that is why mas maganda ang performance nito compared sa oldschool. in short, mas "pino" ang daloy ng krudo sa makina. sounds good pero kung sasamahan mo ng maduming kurdo, nag-iiba na ang story.

problem with this setting, kapag may nagbara sa dinadaluyan ng krudo, hindi nakaka-cope or hindi nalalaman ng ecu na kailangan magpump ni injector ng mas malakas, ang nangyayari ayun, stalling issue. (nakwento lang sa akin ng isang mekaniko ito)

sa oldschool diesel naman, kadalasan na problema naman dito ay yung air-fuel mixture ratio, hence kung mas kulang ang air mas maitim ang usok.

May trade offs kasi dito: better performance (and fuel economy) vs maintenance costs. If you chose to go the CRDi way, it would be the former vs the latter.

In short, we can't have both worlds. In my case, I chose CRDi over old school because I wanted better performance and fuel economy. Saka ko na haharapin ang problema pag dumating kung sakali man. I also see to it that I follow the regular maintenance schedule.

In the meantime, I'm happy with my CRDi ride.

Honestly nakakatakot mag CRDi with our diesel. The parts are WAY more expensive than old school diesels. Everything from the fuel pump, injectors & turbo (VGT) is more expensive. Lalo na siguro yung mga Hyundai if they are using piezo injectors already. Tapos most of them hindi mo ma rebuild dahil throw away type daw. Definitely more powerful and a bit more efficient. You get the same fuel economy even if you run a bit faster than the old school ones. Pero running cost is higher. I seem to change out filters on the CRDis more often. Personally if i could still get a good N/A old school diesel I'd probably just get a turbo on it.

I got 300Tkm on an a/t D22 with no problems whatsoever. Tumatagal talaga with proper maintenance. Problem with old school diesels is old school din ang body, suspension, interior, etc. And the ones that are sold today are way underpowered.

thank you sir marc & ben for the clarification kala ko kaya 5years lang ang warranty ng hyundai eh after that masisira na...
diba merong fuel filter/water separator ang CRDi engine? Downgraded yata sa Euro II ang PHDM na CRDi that's why its supposed to cope with "dirty" diesel we have... ang common rail naman constant ang pressure on all injector lines kaya consistent ang power unlike sa old school... and the variable turbo certainly improves the power boost. pwede kaya lagyan ng VGT ang old school diesel?
regarding maintenance... i think even if it is old school diesel engine kung di naman regular ang PMS eh mapapamahal din in the end...

here is my thought on this subject matter:

CRDI - i prefer this engine type simply because of its new, improved & advanced technology aside from its oozing power performance, fuel efficient (kung hindi ka pedal flatter)..

Old School - i owned one before but sold after a few years due to relatively short lifespan and high maintenance cost in the long run due to used and abused not to mention being smoke belcher..

Maintenance:

CRDI - yap high maintenance but can be offset if regularly follow the PMS sched. if under warranty and ... the best part is if the warranty expired that is the only time na malolower ang cost ng maintenance nya because mas cheaper ang (maintenance & spare) parts outside casa, fuel requirement is not problem as long as you fill up w/ a known brand w/ no issue of being a flooded station..notion: bago kasi kaya maganda and always interested in new technology ganyan naman po iba sa atin, di ba?

Old School - based on experience, low maintenance but once any engine part break loose others would definitely follow suit and sometimes halos same cost din w/ the new brand (car) parts..another notion: luma kasi kaya madali masira but durable if maintained properly lalo hindi choosy sa fuel requirement..

IMO lang po and not speaking for everybody who owns Old School Engine type...

Own opinion ko lang po:

Old school diesel engine mausok kahit regular ang PMS. Kung itaas ng gobyierno ang emission limit poaano na lang kaya ito marehistro sa LTO. Masisira din ang fuel injectors at fuel injection pump kung mahaluan ng dumi at tubig ang diesel oil na pumapasok sa mga ito. Easy to repair nga lang siya at mas mura ang parts. Pero ang pinakamalaking pinagkaiba nito sa crdi engine ay ang power output at emission. Number one na nakaka dumi ng hangin ang makinang ito. Ang repair at maintenance cost ay pwede natin bayaran pero ang pollution na magdudulot ng sakit sa atin at sa susunod na generation ay hindi natin kaya tawaran

CRDi engine mas malakas ang power at mababa ang emission, resulta mas malinis na hangin para sa atin lahat. Tulad din ng old school engine masisira pag marumi ang diesel oil na makakarating sa fuel injectors. Parehas lang silang masisira ng old school engine, medyo mabilis nga lang sa crdi kasi mas mataas ang fuel pressure. Regular maintenance din ang kailangan para maiwasan ang early break down. Suma total ang requirement ay clean diesel oil (kahit euro 2 lang tayo), meaning walang fine metals at tubig ang ating ikakarga sa tanke. Regular fuel filter change is a must. No problem sa LTO emission test and registration.

Pinili ko ang crdi engine Tucson gen 1. 3 years old na ngayon pero wala pa na experience na fuel related problem (Knock on wood) kahit once ko pa lang napalitan ang fuel filter. Odometer is now 40K Km. Nakakatulong pa ako sa pag minimize ng air pollution

CRDi syempre! Do you see any new diesel engine designs NOT using CRDi technology? CRDi engines ARE durable, our Trooper is now 8 years old with no major repairs. Replaced injectors once free of charge, replaced turbo once at a pretty low price (forgot the price ), add to that the usual things that need to be replaced like the filters and timing belt and that's it. It still has very respectable acceleration and runs pretty much like new, better than new even. Maintenance may be a bit costly for some (latest maintenance I had to buy 8 liters of Besco motor oil at 3.8k, the two filters combined at about 1.4k, and then 5% cash discount at Isuzu then pinakabit somewhere else for just 400, since Isuzu charges 2k for labor) but its really worth the money.

For me Common rail technology too.... btw CRDI is patented to hyundai thats why you wont see any CRDI badge in any other brand. just like honda's VTEC.

back to topic, i cant see any point why would you choose an old school diesel vehicle over the newer one. Kasi for me any vehicle that has common rail technology will cost more than the old school diesel vehicles, and if you can afford one for sure you already have considered the maintenance cost of it. same goes with an old school diesel, kung yun naman ang pipiliin mo for sure sa edad niya pag kakuha mo mataas narin ang maintenance cost nun kasi madami narin paliting parts maski well maintained in short medyo masakit narin sa ulo. kaka repair palang after a month may problem nanaman.

also its like taking a step backwards.... IMHO lang naman po....
