Which OIL recommended for the B16b


This is my first post here so it should be interesting :))

I've done a lot of research to find the best oil to suit my engine (B16A2) the climate , polution , oil rate change ; i live in bucharest romania , the climate is verry severe if i my say so , the temperature drops and get high verry often so the oil is verry diffcult to choose . The other part of the equation of choosing the oil is the level of pollution where the engine is most exploited . So after a couple weeks i've come up with this charts , they are split between grade , brand etc. :

i'm using now Eneos 5w40 (US) , Before Castrol magnatec 5w40 (EU) next Royal Purple or Valvoline (us)

Blue (Pao) Purple( bio_ester) Green ( ester ) , orange ( sintetic ) , Red ( sintetic-blend)
Brand's : Eneos (us si uk) , Fuchs/Silkolene , Motul , Royal Purple ,Amsoil (us si uk) , Mobile 1 (us) , Valvoline (us) , Shell , Esso , Selenia , Gulf , Aral , Castrol (us) , Texaco/Havoline , Liqui Moly , Repsol , Sunoco , Ravenol (EU) , Total , Elf.


Note:

Flash Point :
The flash point is the lowest temperature at which it can vaporize to form an ignitable mixture in air

Kinematic Viscosity
Kinematic viscosity is the measure of an oil’s resistance to flow and shear under the forces of gravity.
Oil has a unique molecular structure, and larger molecules create greater resistance (higher kinematic
viscosity). Highly viscous liquid flows less readily under the force of gravity.

Value:

max @100ºC 9.3 (w20) , 12.5 (w30) , 16.3 (w40)
min @100ºC 5.6 (w20) , 9.3 (w30) , 12.5 (w40)

High Temperature High ShearDViscosity cPs @ 150°C (HTHS)
It determinate lubricants viscosity under severe temperature and shear conditions in the combustion chamber. To prevent premature wear of the lubricant is important to maintain their protective viscosity in conditions of severe operation.In generally manufacturers do not really like this to be made public but we can find value in standard ACEA aporx. :
So if that oil is A3/B3, A3/B4 and C3 then HTHS is greater than 3.5.
For A1/B1 A5/B5 HTHS is less than 3.5.
Attention is about standard ACEA-2004, NOT 98, 97 or another old!
Min value: 2.6 (w20), 2.9 (W30), 2.9 (W40) (only for group 0w40, 5w40, 10W40), 2.7 (W40) (for group 15W40, 20w40, 25w40)

Pour Point
Pour point is the lowest temperature at which lubricant maintains the pour property
Max val -40 ° C

Total Base Number (TBN)
The measure of lubricant reserve of alkalinity which controls acids formed when burning.
The higher value the more effective is in combating the corrosive effects of wear and engine for a longer period of time
Min Val. 6.0

Cold cranking viscosity (CCS)
Indicate the dynamic viscosity of lubricant at low temperatures and its shear. Under these conditions is directly related to lubricant viscosity and engine starting rotation.
As the value is even smaller engine will start (spin) more easily at low temperatures.
Max val. 6600 @ -30 ° C (5W) 6200 @ -35 ° C (0W) 7000 @ -25 ° C (10w)

Sulfated Ash
Indicate the concentration of known metals in oil additives. When phosphorus is absent, boron, calcium, magnesium, sodium and potassium and zinc sulfates are converted into the oxides.
The amount of ash remaining after burning petroleum products or ingredients are inorganic impurities it contains
Max val 1.3

Trying to understand the tables but its quite hard because im not farmiliar with telling if the oil properties are good or not.


Can someone simplify it by giving say a list of the top 3 5w40 oils:please: as this is the grade recommended for the b-series engine as an alternative to 10w40
 
Ok , let me simplify the chart for everyone. For me the are 3 most important things to look out
1. TBN ( total base number)
according to the value , will determinate the oil chage time intervals and the protection against acids and wear. let say that the values 5-6 the oil change will be untill 8000 Km (5000 miles) this is for a poluted area where the engine is most exploited .
2. High Temperature High ShearDViscosity cPs @ 150°C (HTHS)
the higher the value the higher the oil film will resist breaking at high temperatures in exterme and diving condition ( rally , track etc) providing engine protection.
3. Cold cranking viscosity (CCS)
Smaller value the engine will start (spin) more easily at low temperatures
Max and min values have explanations so you can get an idea what kind, brand and gradation of oil pick depending on the season, driving style, competition
 
Thanks for that info^^^^^it does simplify things:nice:


Its hard to compare some oils due to the fact that some of the data is incomplete but the motul 300v power seems to be a good preformer.

Is the Silcolene/Fuchs Pro-S as good as people say it is??
 
Something to consider with the data is if the manufacturers don't release a lot of the data, the chances are they want to hide it as it's not that impressive.

Also figures don't mean everything. Results are the important thing and based on things we have heard back from our sponsored drivers (and their engine builders) as well as customers, I can confirm that the Pro S is a top end oil, as good as anything else out there.
 
Just a quick q here;
I have a can of millers 5w30 race oil and a can of motul synergie 10w40.

Which would be the right one to use?
Ive always used 10w40. Engine always liked it and didnt burn any. Im thinking i should stick to it......

:nice: +1 i could not say any better.

The best reveiw of the oil that you inted to use is the person who used the brand/gradation/type of that oil.

The Millers is the better quality, but if it's been fine with 10w-40, use either. Mix them together if you want.

Sometimes they are the best reviewer, but sometimes they don't have very high expectations. We get some people who say things like 'there is no need to use a full synthetic as my car lasted to 120k on mineral oil', but then I know of plenty of the same cars that have lasted to 200k. I listen to our sponsored drivers as they abuse the cars and if they bear up to the treatment, they oil is pretty good. One driver took his car to his engine builder at the end of the season and the builder thought he'd only done a couple of races, but he'd done the full season, using Motul 300V instead of average oil.
 
You sure about that? What engine? In the past engines have been run in on a mineral oils to help bed them in, however now tolerances are so good on modern engines due to materials and construction methods running in isnt really required in the same way it used to be. Some engine are so well built they run very thing synthetics from the first turn of the key.

Probally the only decent post here. Your missing a few;

-NOACK Volatilty
-Four-Ball wear test
-High temp/high shear viscosity

I suggest people to read this long informative 10 page long post by 'bob is the oil guy'. It will help you understand more about oil and help you decide what suits you.

http://www.bobistheoilguy.com/cms/

There are lots of variables like;

-which oil was the engine tuned with?
-daily drive?
-track only?
-etc

A short tip i'd input though is engine is most critical during cold startup.

Oil grade and properties between all oil brands are different. Research is needed to acquire 'the best oil' available. And if your one of those who buys into thinking 'because its branded 'MUGEN' its the best!'. Your an idiot. No offence. Just put some time into research. it'd be worth it like it did for me. :nice:

I have used Pro s for the past 4 years, never had any problems, in my DC5 or CRX track day car. The CRX would do 80 laps on a track day with no problems, i did that for 2 years and used it on the road a drive to Germany 25 laps of the ring. Really is top stuff.
 
I just ran Honda's 0w20 oil for the hybrid cars and it was excellent. Oil came out cleaner during its 5000kms interval than anything ive used so far. Engine more willing to rev.

Running Amsoil 0w30 now

Next will try Motul 0w20 High RPM oil.
 
Because 0w-20 oils have a small viscosity gap, they don't need a load of additives to maintain the gap, making the oil more stable.
