I Go for Synthetic Fluids..
If you plan to keep your Car till 200K Mileage and more..
If you use Honda use Honda Fluids.. Same with other makers..
The Car Manufacturers knows their own engine /specs..
And they Spend years to Develop thier Own Fluids/Oils for it to Run Efficiently..
Kahit mahal.. Of course Pag Original/Synthetic medyo pricey talaga..
You get what you pay for sa Synthetic..
