To the professionals in the house, i will like to seek your opinion and professional advice .

Background:
I love toyota sienna due to its roomy and large cargo space. I want to get it for personal use most especially for the comfort of long journey with my family once in a while.

I discovered 2004-2010 Model year are of the same generation.

In the course of pre examination for average price, one of the seller discourage or let me say he gave his opinion that 2008 carried big engine and consumes more fuel that 05 or 06 will be better.
My further findings shows 2006 is equipped with 3.3 L engine while 2008 is with 3.5L.

Please, i will like to know
1. the implication of this big or small engine of a thing
2. The fuel consumption
3. Any other issue that is related to either of them

3.5 has a better performance and fuel economy than 3.3. When you get the 3.5 tell your mechanic to check the oil cooler hose and confirm its metallic not rubber. If it's rubber, please buy metallic and replace if it's not too costly to do or better still always check the oil guage regularly, if you notice oil shortage just check the oil cooler hose asap for leakage.

The hose can fail while in motion and Engine would knock, Once aluminum Engine knock, nah replacement sure pass.
