Mineral , semi synthetic or fully synthetic?

[leinahtan]

Hi guys! Pardon my peskiness.

Which one would you use if you were in my position?

1. Shell Rimula R4x: multigrade, (mineral oil?), 15w-40 with a CI4 rating * 205/ltr

2. Shell Helix Diesel hx7: multigrade, (Synthetic or semi-synthetic?), 10w-40 with a CF rating * 365/ltr

3. Shell Helix Diesel hx5: multigrade, (mineral oil?), 15w-40 with CF rating * 250/ltr

4. Top1 HD plus:: multigrade, semi synthetic, 10w-30 with CI4 rating * 300/ltr

My plan is if I will choose option 1 or 3, OCI is at 5k, and if i'll choose 2 or 4 at a longer OCI perhaps 8-10k?

Isuzu recommends 10w-30, which is pasok na pasok ang Top1 plus a high CI4 rating.

Would be using Bosch oil filter rather than Vic. Walang Baldwin or FG talaga eh.

Any suggestion/s?

Again, advance apologies. Thank you.
