pouring gasoline engine oil into diesel engine

[snowbound]

just curious, will it cause engine damage if you will pour engine oil designed for gasoline engine into a diesel engine? i have observed people doing this especially in govt vehicles when oil for diesel engine is not available, they pour gasoline engine oil into diesel vehicles.

[dennis powell]

only one thing that i can say, is that they dont know what they are doing,it may hurt the engine and also they put their selves in danger,they dont even think that they create a bomb for themselves.

hmm...could you please elaborate?

basta may API -CF rating puede po... ibig sabihin po nung rating na iyan, puede sya sa diesel....

a diesel engine has higher compression and higher temperature levels than a gasoline engine, ergo you use a different oil.

Try replacing one with the other, and voila! you got a busted engine.

was using Mobil1 before when my ride was new from 1k to 30k on my diesel pick-up and it now has 164k w/ no problems. yes as long as diesel rated ok lang.

honestly, i read the thread on engine oils and cant really figure it out due to some technical terms. sometimes we use the government issued petron engine oil designed for gasoline engine on our diesel vehicles. i checked the cans and there is 20-40. does this mean this oil cant be used on diesel engines? thanks.

you can use it specially with sae 40 but not for long time.
dsiel engine oil has higher boiling point (rating) than gas oil, if accdently use 10-20w gas oil for along time mdaling lumabnaw un katok abutin mo hehehe

check the label API claims of the oil first. if it says SF/CD or SG/CD, then you can use it interchangeably. Normally, our vehicles have recommended grades based on our engine, so if it says, SF rating. then we can use any SF rating or above. S stands for Service (gasoline engines) and C for Commercial (diesel engines). The higher the second letter, the better the quality. Of course, if money is a constraint, then just use the lower grade possible for your engine.

puwede ko kaya gamiting alternative yung API CF SAE40(delo silver monograde) kahit na dati kong gamit na oil ay API CF-4 15w40(rimula-x) mahal na kasi ng rimula-x ngayon?

Pwede as long as your car only requires CF rated oil. But a multigrade CF-4 is better than a monograde CF oil. Downgrade yan. My advice is to use a multigrade oil. Kung mahal ang Rimula-X try mo sa Petron or Caltex. Meron din oils ang Total, Castrol etc...

When checking oils for specificity to gasoline or diesel engines look for the S or C. The API-Sx rating is like the spark (for sparkplugs) for gasoline engines, while the API-Cx rating is like the compression for diesel engines. Diesel engine oil has soot protection, gasoline engine oils do not. You won't get as much soot protection from the gasoline engine oil but if the weight is similar you should have no problems.

I have a cousin who was in the motor oil manufacturing business. He claims that many times there are no physical differences between the diesel and gasoline engine oils.

It makes economical sense though - if you have an oil plant, why not just come up with one production line coming up with a product suitable for both diesel and gasoline engine? The only thing different would be the packaging and marketing.

The fact that an oil product was only tested and certified for gasoline or diesel use, doesnt mean it wont pass the test for the other.

In the same way, many of us here aren't certified to drive in certain countries, but that's because we havent taken their test, not because we won't pass.

I used to work as a lab analyst in a power plant in Navotas, I check the oils upon delivery, I know a little about engine oils but I'm no expert, Iba kasi additives ng engine oil for diesel engine kesa sa gasoline engines, mas mataas ang TBN ( total base number) ng oil for diesels para makontra yung acidity ng diesel, if you will use a purely gasoline engine oil prone sa corrosion ang internals ng engine mo

Well probably nothing that he can see. There is a reason why oils are diesel or gasoline rated.
