Well, tribology is as we say the bastard child of mechanical engineering and chemistry. The complexity of both makes it a very complex topic, so people like to simplify it mah.

When you going to turbine level quantities and potentially non-Newtonian fluids, we already sit down an calculate shit like Reynolds numbers and shear viscosity effects, so I can understand why people prefer the butt dyno.

That's why we pay the Tribo experts so much laugh.gif

But as for me, if you have a good baseline and one oil works well for the car, it'll be fine. The key is to choosing the right characteristics for the right engine, and the best place to start is the manufacturers recommendations. Even with all our lab equipment, test systems and literally a giant oil company behind us, we always start from what the OEM/Vendor recommends and assume it's the best.

hahaha good one bro.
interesting way to start a morning (or for me ending, since im on night shifts)

totally agree with you right there and that's what i've done previously and right now. thumbup.gif

Yes you can stay with 6 months for semi and a year for fully - provided the additive package is sufficient and it is a genuine product from a reputable brand and especially if they market/endorse it like AMSOIL XL/Signature series or Mobil annual protection.

Otherwise stick with 6 months even with fully.

I am wondering the oil filter can sustain up to 1 year ? Should i stock to the car manufaturer ori oil filter if i want to use the oil for 1 year ?

If low mileage, I think no problem.

It's your car, your choice.
Stick to manufacturer recommendations if you're in doubt and especially if you're still under warranty.

Any idea how to get the oil with that rating?
Previously send sc honda with 0w-20. Now already had the warranty expires.
Dont forsee to buy online due to risk of fake oil

Tesco always have 5w40 only under shell helix.

Since its easier to get hold of 5w30 it shouldn't have too much difference with 0w20 I think?

Reputable sellers/dealers

Can try Penrite, AMSOIL, Motul, easily can get that viscosity rating

To me, w20 and w30 not much difference in availability.
Albeit Penrite racing already discontinued 0w20 so in that sense you're correct.

Ultimately it's your call, I just prefer sticking with 0w20 cuz of my experiences and oil pressure /temperature gauge monitoring.

For shell, usually the bottle colour dictates the range :
Yellow = mineral
Blue = Semi synthetic
Grey = fully synthetic

Didn't know that! Thanks, so Shell High Mileage 10w-40 is semi-synthetic.

Not sure if can use fuel additive like Liqui-Moly/ Marvel Mystery Oil for this kind of engine oil?

Those reputable brands that produce engine oils, they spent many millions and a large team to get their additive package right within their products. So i guess the requirement is at least adequate for normal driving.

Unless you really need something really specific due to your driving environment or because you consulted some engineering expert about it, additives are quite a waste of money. But mostly don't do any harm.

Just use good reputable oil, no need to waste money on those additives, they can actually make it worse!

I support anything that's value for money. 😂 But if I were to have a nice high performance car and spend on the best oil then I'd choose Amsoil.

Their dominator series don't have really thin viscosity and signature series are really meant for long OCI

bummer really.

Signature series is damn good already, better or at least just as good as any other top oils out there, more than enough for any street cars. Price also actually much more reasonable than the overrated Motul or Liqui Moly for example.

Well I'm a Motul (and somewhat liqui Moly for Motorcycle cuz 66 Speedbike lol) fanboy so I would disagree on overrated la.

It is true though that you are paying a premium for marginal gains, but that's how it is in any hobby or even just about anything in life that as you want to attain more, you'll have to deal with diminishing returns.

Personally, it is a company's (both Motul and Liqui Moly) reputation is what got me sold - they are both very long established, and both very actively involved in Motorsports.

Liqui Moly is even the official Moto2 Moto3 lubricant.

Then, there's base oil. Motul more on ester and LM on PAO.
AMSOIL generally group 3 then mixing PAO/Ester (if any, they don't advertise a lot)
There's also recent API /SAE recent studies on LSPI, and AMSOIL overdosing calcium could be a concern for high performance/direct Injection vehicles.

Well if looking at reputation, Amsoil was actually the first to make FS oil wasn't it?

I truly doubt Motul or LM are better in the real world than Amsoil despite having better base oil. Maybe you can try then do oil analysis test to compare with your favorite Motul and LM.
