lets put harming engine aside for a short while.

reason for api ratings to reduce ppm content is to reduce emission levels, and potential cat-con premature damages/wear

granted, if you drive an old car, no cat-con and not give a shit about emission/environment. sure, feel free to use diesel engine oil/HDEO.

i am merely following my owners manual and last i remembered correctly:
- they did not recommend diesel engine oil
- im no oil expert to determine the use of diesel engine oil
- im no car engine expert to determine that it won't cause long term side/harmful effects to my car engine
- just spent a fortune to overhaul my car last year, im not risking my seals/internal parts for potential accelerated wear lol

So bro wunpeng, your magna M1 S710 engine oil that you are using having a TBN 9,is it a diesel engine oil?

http://static.lowyat.net/uploads/attach-98...-1343728215.jpg, best part is under the performance column , there is this mercedes 228.1 , please open this link http://bevo.mercedes-benz.com/bevolisten/228.1_en.html.. they are all diesel engine oil

amsoil xl http://www.amsoil.com/storefront/xlo.aspx , also TBN 9, so it must be a diesel motor oil too??

Caltex Havoline 10w-40 https://cglapps.chevron.com/msdspds/PDSDeta...1&docFormat=PDF, having TBN 10.9...also hdeo??

Torco SR-1 5W-40 TBN 7.5 http://www.torcousa.com/technology/TDS_SR-1%20MotorOil.pdf

if this model is correct the figure for flash point is also wrong.. 410 deg F = 210 deg C



My figure was right. Your link was also right

As salam,

HDEO harming our engine?no evidence...my friend also my sifu are using it for 15 years both on car and motorbike...

I have read so many forum in US ans europe..they using it even for drag race,dirtbike race...

Every engine oil must have 10 basic additives either passanger car engine oil or hdeo...


Again i'm not encourage all of you using hdeo,but give a try...delvac 1300,pennzoil longlife,bhp2000,valvoline premium blue to name a few..most of them are API S certified...

For me,after 3 years using it on my Saga BLM,i'm very satisfied...

Didn't i mention i got a friend who using mineral hdeo who manage to revv up to 13000 rpm and still smooth after that...

Just my 34.5 sen

I think it is because it is a Multigrade Engine oil, so it need TBN content. Correct me if I am wrong.

no.....even monograde oil have the TBN...but a bit low...coz the additive are not enough to get the higher TBN...(but HDEO monograde got good TBN)....

TBN is important to clean up your engine.....the higher the better...but not more than 12...

Comment on this monogred then http://www.ro-quip.com/Technical_Docs/Roya...or%20Oil_ps.pdf

I got a friend family business using a lot of lorry, especially diesel one, they are using a engine oil for so many years, then don't know TBN is needed in the engine oil and they also don't know what is TBN. They got a lot of engine blow off this year... When they test off the oil they use then only know the reason. Now they stop to use the oil they use before. They switch to another brand of oil which TBN included, they directly become distributer for the oil because they can use 3000L of oil within one month.

Using cheap oil without understanding your engine requirement is dangerous. Understanding oil and your engine safe you money and trouble. TBN is mention in the datasheet, but again need to check the TAN no of the oil..Eg No point having a oil with TBN of 9 but TAN of 4. The oil cannot last long too.. Doing VOA and UOA is the best way out..

Actually, picking a correct engine oil need not require a rocket scientist or a Phd in Chemistry. All one need to do is, read the car manual and use the oil specified and change at correct OCI. Case closed.

Unfortunately, vast majority of motorist never read their manual. Take a example. There are plenty of Proton car owner but according to the manual, you can use 10W30 but not 5W30 in Malaysia. But 99% of owner don't know that because they never read their manual. May be Malaysian don't know how to read?

I thought we only need to look at the number behind the "w" ?
In my observation, most 10w30 oils are mineral based, while 5w30 are mostly semi syn.

most 10/30 oils are mineral based ke ? ya meh ?

That is a great mystery as to why we can't use 5W30 but that's what is written in the manual. I would like to know the answer also and until I do, I just stick to what the manual said because I am not a rocket scientist.

multigrades, the further the viscosities are from each other, the more the polymers

where can we do VUO or UOA in Malaysia?

Oil for saga blm auto,any recommend .

10w40, liqui moly or torco

newer saga i thought the original specs is xw40 right? cant go xw30?

btw, for almost all the saga (IINM) having rev cuts/limits on the ecu, i am not even sure if torco's worth it lol.

and proton uses xw50. LOL

I don't know which Proton or what year's Proton you are referring to. But I have seen a couple of Proton in present day showroom using 10W30 for ambient temperature up to 40 deg C.
