As salam o alaikum
I own Khyber 97' and odometer reading's have been reverted to zero and now it is almost 20k.
I would like to ask you all that I want to check/inspect by myself, how to check gasket just to make sure it is in a good condition. I bought this car 6 months earlier. After buying I have spent my time on my car's engine at that time my mechanic have inspected my gasket and said its okay. I don't know previous owner had replaced gasket or not.
Previously I have done a blender of using Guard motor oil 10W-40 and recently I have read a post by a senior pakwheeler stating that "once you have used a thick oil (20W-50) in older car. Never switch to a thin oil like 10W-40 etc... it will cause damage to your engine and cause leakage in gasket". Do you people think that this really happen?
Now i am starting to worry about gasket.
When i was using 10W-40 my engine was running so smooth and response was so strong but engine was reducing oil. Mechanic asked me to get oil change after every 3k KM but engine reduced oil before 2.5K.
Is guard a reliable motor oil or should i switch to Havoline CNG or any other?
Mechanics ask's to check for any bubbles in radiator. There are no bubbles Alhamdulillah. But I need to make sure for my self that it is in good condition.
Need experts opinions about this.
