Oil type
What type of oil are you guys using in trucks? What is the capacity of 2000 suzuki engine for refill?
Usually 10-30W oil with a capacity of 2.9 liters/3 qt. should be fine.
Sukuki Carry service manual mentions 10-30W oil with a capacity of 2.9 liters/3 qt. with filter.
My personal choice is usually 5W-30 oil with a capacity of 2.9 liters/3 qt. I feel my engine runs smoother when I used this oil variant.
The best way is to make use of the engine oil finder. This ensures you get the right specification oil for your Carry. 5w30 engine oil and 10w40 engine oil will be suitable for you. Experts recommend you change your oil every 3000 miles. It's possible that you will need to top up your oil in-between services as well. To avoid paying high garage costs, it's a good idea to keep a 1 lite top-up of oil in your boot. Oil capacity for a four cylinders engine is usually around 5 quarts.
