My first oil change since on CNG

[Genie47]

Since I run exclusively on CNG save for the starting and idling.

 

Marked differences in the used oil. Mainly from the smell. In my past changes, there is a heavy petrol smell from the oil. Now there is none! Seems like the oil is indeed diluted with petrol a lot for my car.

armpit smell?

 

u gg to do UOA on this?

[Genie47]

Next round do UOA. Now too early. Let system burn more CNG first. Then I got this CEL to take care of.

Besides smell, does the oil look cleaner with CNG?

[DarkLord]

Huh? You changed to CNG for almost a year isn't it??

[Genie47]

No. Still the same brown color instead of the golden color you get with fresh oil.

[Genie47]

Last time it was on 25% CNG and the rest on JB petrol. Now it is 95% CNG and 5% JB petrol.

How often do you run on petrol since it acts as a cleaner and lubricant as well?

 

If I'm not wrong, CNG is dry gas?

 

Tks.

[Genie47]

When it starts, when it idles. That's it.

Hi Genie,

 

What grade of engine oil you use? I heard with CNG, cannot use too thin oil.
