How can you tell the life (in km) of engine oil???

Question

Different auto mechanics tell different milage of engine oil. Some say 3000 km and some say 4000 km. My car is 1000 cc 4 cylinder using bi-fuel i.e. Gasoline and Compressed Natural Gas. What should I look for on engine oil packing?

Answer 1

Follow the auto makers recommendations, and when you change the oil have a sample sent in for analysis. That will verify if your schedule changes are working, if you may go longer or need to shorten your change intervals.

I operated a fleet of 100+ trucks, and we did that in a regular basis, It validated my service schedules as good and alerted me to early potential failures before they did fail, saving me lost down time on the road and ill-will with my customers.

Whether it is a car, truck, bus, or any internal other combustion engine this will work. No mechanic can reasonably or simply look at oil and say it is good or not. If oil is doing it's job, it will turn dark relatively soon after a change.

Answer 2

The condition of your engine has the most to do with how long your oil will last. Put a drop of fresh oil on your fingers and feel how slick it is. Now you can compare that to a drop off your dipstick. You can actually feel when the oil is losing its ability to lubricate and cool the motor. Another test is to sniff the dipstick. You can smell a slight burning in the oil if it is getting old and needs changed. Look in the owners manual, or call the dealer for the specific type oil you should use in your engine, and their recommended maintenance schedule. Best advice, however, is change the oil every 3000 miles, or use synthetic oil; keeping track of ALL the fluids in your vehicle is a common sense rule to make your engine run its best. Lastly, remember that 30 wt. oils are thinner than 40 wt. use the lower number as temperatures fall. A multi-viscosity oil such as 10-30 acts as a thin oil for easier starts in winter, but when the engine reaches operating temp it then acts as a thicke oil for smoother, cooler running.

Answer 3

the thicker and the darker the older the oil is. regardless of what fuel u use, u should change ur oil in 5000 kms (thats around 3000 miles) unless u use synthetic oil, that goes for up to 15000 if u may.
good luck changing oil!

Answer 4

3000 miles

Answer 5

be on the safe side. 3000

Answer 6

if your using natural gas go for an oil that is recommended for gas users its ok if your using normal fuel and oil only needs to be changed every 10000km anybody who tells you otherwise is an idiot

Answer 7

3500 km :)
