Hks 10w45 any good in a b16b?? Opinions?

Also engine oil has come a long way since honda put oil spec's on there engines back in the 90s

I agree that's why I'm using different oil to what honda recommend.
But as mentioned these oil topics are like opening a can of worms, like you have said use what works for each of us.
 
Very true different motors and different driving styles/conditions will vary from engine to engine ,
Bottom line know what your engine likes and not
Like .

Agree with @b16 mini on this one. Have seen a lot of this going on lately in various threads.

With regards to what grade of oil to use, IMO, for our climate there is no need to go lower than a 10w oil for a B series engine.
 
I was just saying that I was using 10w40 motul and other 10w40 oils and found it burned off a bit
So I looked into a solution,
In the process found 5w30 does not burn off
And also is better on cold starts were engine damage
Is done ,
And has near the same viscosity when cold as 10w40
Is when hot and both have NEAR the same viscosity
When hot .
That what I said makes sense to me to use
The 5w30 fully synthetic.
 
If that does not make sense this might.

The above SAE table describes the typically recommended viscosity grades based on ambient temperatures, leading people, in my opinion, to think that 0W40 oil is overkill for British conditions.As noted, Synthetics usually have a naturally higher viscosity index than even the artificially increased VI of mineral oils.Therefore, a 0W40 is better than a 10W40, since both offer the same viscosity (SAE40) at running temperature, but the SAE 0W will circulate more readily during a cold start than a SAE 10W.It is patently incorrect, as is often stated, that 0W40 is too thin when compared to a 10W40.How is it too thin? In fact the performance of a cheap 20W50 sheared down in service is likely to be far worse than that of a 0W40 at running temperatures.See Graph 4 below

Lee, your still miss understanding..
At running temperature a 5w40 and a 10w40 will have the same viscosity, A 5w30 how ever will not.
A 5w40 will offer better oil pressure when hot compared to a 5w30 because of this difference.
This is why boosted people tend to use 10w50
 
Thing with oil is, sometime it is down to peoples opinions and experience. Some people swear by 5w30 and some don't.

Think the best thing you can do is go by that Honda handbook and get a good brand of oil.

Iv not tried 5w40 yet but I just might on
My next oil change.
And see how it goes verses what I'm using now ,
As I pay 20 odd euros for 4L of valvaline witch does not burn off verses 45 euro motul that burns,
The tolerance on honda engines are tight which
To my understanding would be better to have
Oil with low viscosity? On less you build a
Engine with not so tight tolerance,
Calling for a higher viscosity oil ?
I'm only going by what I understand and read
I'm sure you and others have way more knowledge than me on this issue,
And I'm happy to learn along the way .
 
ive always stuck to a quality 10w-40 on the trackcar, well until this current engine.
The oil pressure scares me with a 40grade in.
 
Might do!
I have been thinking of chopping the Civic in for a V8 Vantage. - But I am getting a sniff of the racing season now.
