This Shell Helix HX5 15W40 is one of the best and powerful mineral oils around with SN and ACEA A3B3, and I consider it as suitable for your Honda.
Unfortunately you find it a bit sluggish.
If you must move to a xW30 to improve engine 'sluggishness', then I recommend you another powerful mineral oil from Shell Helix HX5 10W30 SN ACEA A3B3

Well ..... because of specifications ACEA A3B3, and to a certain extent oil change intervals,price and availability etc.
I'd used mineral HDEO dual rated with A3B4 in carburretter Wira for 8000-10000 km oil change.
I too had semisyn A3B4 in Avanza for 15000-16000 km oil change.
The fullsyn in Avanza today would be for a minimum of 16000 km, likely 18000-20000 for a start, IDK.

You may consider a semisyn A3B3/B4 if OCI exceeds say, 10,000 km.
What's your intended oil change interval , btw?

At 5k km, any mineral SN/SM/SL/SJ without ACEA A3B3/B4, whether branded or unbranded, would do.

For the same buying price, you could get SN A3B3 in branded Helix HX5 10W30 or 15W40 with the option to extend OCI beyond 5k km.

A typical A3B4 semisyn, as in a Magnatec Stop-Start 10W30 SN A3B4 would likely do > 10,000 km and beyond , but it generally costs more, even after discount , if any.

Mineral and mineral A3B4 are 2 different things.
So are semi synthetic and semi synthetic A3B4 are 2 different things.

Helix Protect 0W30 A3B4 is a fully synthetic with a minimum High Temperature High Stress HTHS Viscosity of 3.5 mPa.s .

10,000 km oil change interval is easy meat , could go further if you are adventurous imho.

B1-B5 has a lower minimum HTHS viscosity of 2.9 mPa.s , it may be ok in a turbo engine on light duty use but I personally prefer A3B4/C3 oils with higher min HTHS viscosity of 3.5 mPa.s with options to whack the Hilux turbo engine once in a while or for Italian tune-up.

Do consider a C3 in future at similar price point for its far superior additive requirements compared to A3B4 .

FYI , ACEA C3 was introduced into Europe market in 2004 in conjunction with Euro 4 diesel launch.Malaysia's diesel is Euro 5, go figure.

I am impressed with my several observations of cleaner/better blotter spot tests performance of C3 oils in petrol engines vs non-C3 oils in my thread so far.

I agree with the two posters above suggesting use of HDEOs which typically carries additional OEM approvals , for your turbo diesel Hilux classified under Light Diesel vehicle.
API CI-4/ACEA E7 are high SaPS whilst API CJ-4/CK-4, ACEA E9 are mid SaPS HDEO's.

As regards ACEA B1-B5, C3 HTHS, TBN, acid neutralising properties etc which digresses from TS thread topic, I suggest to address it in my other thread on blotter spot tests in say, next 2 weeks or so and hope to keep you posted.
