im using semi synthetic then change oil every 5k for a crdi engine.
hataw pag ginagamit ko, so far no change since day 1 sa performance.
our drivers have noticed great improvement after linisin yung egr of our accent.
nasa 1k lang binayad namin sa mekaniko for egr cleaning dahil kapit bahay lang si manong.
since mahal nga ang turbo kapag nasira, for added protection, nag palagay kami ng turbo timer.
at shmpre kelangan din talaga na tama ang rating ng engine oil at least API-CH4 for accent.
meron offer na service ang hyundai QA during my 30t PMS, its fuel line carbon cleaning using a separate machine for this, which is far more better than putting an injector cleaner in the fuel tank. According to them, this process will clean the fuel line most specially the injectors (which is very crucial in a CRDI engine) and will make the engine run like new again, powerful and fuel efficient again. cost of the service is 3,500.00. this is advisable for those who cannot perform the Italian Tune-Up once in a while. i'll give feedback when i get my santa fe this wednesday.
i was just reading the kia sorento manual (for those who don't know, i gave up on the santa fe and sold it then bought a sorento) and it says there that the emission control system (the catalytic converter) needs to operate at a certain temperature which can only be achieved at a certain minimum engine speed and operating time. it says that if the vehicle is used mostly in stop and go traffic, low speed city driving, short trips, etc., then the system will get clogged up with soot and result to less engine operating efficiency and power. to prevent this, and also to remedy, it recommends to drive the vehicle at highway speeds for at least 25 minutes or more. this will burn up the soot deposits and clean the exhaust system. since the kia sorento shares the same engine as the santa fe, and similar fuel system as the other hyundai vehicles (CRDI) then hopefully this info helps.
btw, was at unioil to fill up lately. they now have ULSD diesel fuel (euro 4 compliant, less than 50ppm sulfur). same na din yata sa seaoil and jetti.
the santa fe was an ondoy victim. i already spent 300k on it and still problems were coming out, last of which was the steering freezing up due to a shattered steering column bearing while my wife was driving it, almost causing her to collide with another vehicle. better lose money than be sorry for a lost i can not replace. i'm glad i sold it already as i am very satisfied with the performance of the sorento.
was at Kia congressional this PM, they said they use Zic fully synthetic which is CJ-4 rated.
Modern Diesel fed engine cars that have Euro IV emission certification, have a built in DPF (Diesel Particulate Filter) at the exhaust system. This is somehow similar to the basic function of Catalytic converter for the Gas fed engines, only this one is added with a very intricate and fine metal strainer after it's catalyst to trap the burnt ashes. Once that metal very fine filter is clogged with ash then you'll surely feel the loss of engine power due to restriction of escaping exhaust gas at your tail end pipe. Also if the trapped PM (particulate matters) is not burned to ash then the clogging will be more evident. And para maburn off mo those PM at the fine filter you need to heat up the Oxidation Catalyst minimum of 300degC. kaya kelangan na medyo kelangan ang spirited driving to attain that exhaust gas temp para magstart yung chemical reaction ng Catalyst sa Particulate Matters to burn it to ash Regeneration mode yun. Eventually kapag certain period of driven miles/hours kelangan na din palinisan ng ASH sa isang specialist clean up shop..( i dunno kung meron na nun sa Pinas) so bale this is somehow also an Italian Tuning type for diesel engine cars.
Ang isang importanteng poison ng oxidation catalyst is sulfur again ...kaya kelangan talga na ULSD ang fuel na gamit also to use the API CJ rating na lube oil. (Low ash content)
Medyo magastos ang maintenance talaga ng new type of diesel engine cars...but hey you're helping saving the earth by lessening the impact of your emissions. Tska kaya nga high Torque and HP now ang mga CRDI engines..gamitin naman paminsan minsan sa Italian tuning..do it safely lang....hindi naman kelangan na overspeeding kelangan lang a little above average engine RPM not necessary speed..put it to D3 lang lol. para hindi mag overspeed..high revving lang. Am not familiar with Hyundai engines but some Cars i.e Volvo trucks have lamp indicators that warned you if you need to perform Regeneration..aka Italian tuning.
