As far as my knowledge goes you can use the engine oil and engine oil filter. But, don't know how to use bardahl for engine flush. Can, you please post the pics of oil filter without the box. i.e. by openening it from the box packing. So, that we can have an idea of what is in the box. I think the price of the engine oil is also reasonable. I got 4L can castrol edge 5W-40 for Rs.3,200/-. What is the cost of oil filter and engine flush liquid?
