Oil too dark

**curvis** · March 16th, 2009 02:29 PM

I just had my change oil last Christmas break (3 months ago) and when I had my fuel refill, the gasoline boy asked me when my last oil change was. I was surprised to get asked this question and he showed me that the oil was already dark.

The oil i purchased and used was the best Diesel engine oil Mobil had to offer. The 6L of fully synthetic Mobil 1 cost me around 5k.

(4d56 engine)

Ano kaya ang problem?

imho, tama lang na magdarken agad ang oil. it means that it is working.
ang nakakatakot, is after three months, slight darkening pa lang nangyayari. it means that the oil is not cleaning your engine.

yep.

or, parati ka bumibiyahe sa mga mausok at maalikabok na lugar. lakas humgop ng hangin ng diesel... yung nahihigop nga nappunta sa makina yon.

and besides since diesel pala ang sasakyan mo, pag change oil mo ilan araw lang itim na rin kaagad ang oil mo...

pereho tayo sa gas engine naman ng 2000 revo glx last dec din na change oil ng tignan ko kahapon maitim na. since meron naman akong stock na mineral oil change oil ko na lang DIY, ganda na uli ang takbo, mura lang naman ang mineral oil wag nang paghinayangan.

my question naman sa TS is ilang thousand na natakbo ng adventure since dec.? at baka lang di pang diesel mobil mo? Delvac ang FS niyan. kahit fully synthetic pa oil for diesel hindi bagay paabutin ng 10K kms. at considering na old school rin ang 4d56, any multigrade mineral or your choice pa rin ang bagay. kahit oil change mo ng every 4K kms di masakit sa bulsa at mas ramdam mo ang smoothness niya sure yan

yes.

sa akin, one week, maitim na. the only time i had an unchanged oil color for a long time is around three weeks, when i used Castrol GTX.

pero lahat ng langis na ginamit ko, may changes na after three days.

i switched to shell blue and i noticed that discoloration only happened after 1.5k. can we say that this oil is not good enough? my engine is 4g15 with 75k mileage. oil filter is vic

you have engine sludge, dont matter your using best motor oil like mobile or Castrol GTX only way to get rid of it is to hot tank the block and head then rebuild it back.
