Diahatsu recommends 5W30 SAE or 10W30 either semi-or fully synthetic. Fully synthetic is better oil. Whether you choose 5W30 or 10W/30 depends on your climate. If you have frequent days before zero C, 32 degrees Fahrenheit, you may opt for the 5W30; otherwise, the 10W30 in the one you'll want. Selenia oil tends to be the least expensive of the synthetics and it's a fine oil. (I buy mine at Carefour Suermarket.) FUCHS is also very good and doesn't dent your pocket book. Mobil 1 and Vavoline are quite expensive in Europe, and Motul and ENEOS are outrageous.

I am taking a bit of a guess because I don't have information on such a late vehicle but I think it is a fair bet Diahatsu are using embedded transponder chips in the keys with a steering lock/ignition switch mounted receiver.

That was a popular trend among manufacturers and was the system employed by Diahatsu in their earlier models with a master key and up to three slave keys. They are more likely I think to leave the basic system as it is and just add a remote locking system than to develop an entiely new system at unnecessarily high cost.
They could have cribbed a system from another manufacturer of course...

The Ford PAT system was just about identical and gave little trouble and they bridged the gap by fitting remote locking and providing a remote.
The Renault system was similar but many models were very troublesome as they aged and the immobiliser was soon updated and was integrated with the key "plip"

Both these manufacturers use a dashboard mounted light to indicate whether the immobiliser had been successfully disengaged but I have no information about the Diahatsu other than a note dedicated diagnostic equipment is required for key coding.
I am sorry this hasn't been much help.

May be coil pack or plug

Faulty or blocked fuel pressure regulator?
