Liqui Moly full synthetic. 2qts 10w40 and 1qt 10w50 with the factory Honda filter.
Pros: full synthetic, factory Honda filter
If it’s actually an IAG long block, they spec Motul 8100 X-CESS 5W-40 (or an equivalent high quality 5W-40 full synthetic) because their bearing clearances are set up for that weight, not the thinner OEM oil.
Pros: high quality full synthetic
Amsoil 10w-30 metric
Pros: 10w-30 metric

Petronas sprinta racing 10w40
Pros: sprinta racing 10w40

Pros: Mobil 1 4t, K&N filter
If you are using VW original oil then stick to it and the service interval. 15 years 229,000km later mine is going strong. I did mess up by doing service at 15k km all these years. Sticking to 12k is best. Instead try iftex system D. Makes a very noticeable difference. More important I feel is changing the air filter more often. And compulsorily changing diesel filter every year.
Pros: stick to service interval, air filter change often, diesel filter change yearly
Cons: mess up by doing service at 15k km
Vehicle:
Volkswagen Polo
All in all, that engine oil is expensive, holy liqui moly
Pros: null
Cons: engine oil is expensive
cu cat l am folosit mai mult am ajuns la concluzia ca castrol e un gunoi, cel putin pt motorul meu si am trecut la uleiul original ca sa nu le mai incerc pe toate
Cons: Castrol e un gunoi
