Changing from 5w-20 to 0w-20
Hi guys, i have a 2003 civic with a 100k on it. Ive been reading on mobil1's website that my car which uses 5-20 can be able to take 0-20 and become more fuel effecient. I live in chicago right now, and its frigid cold, so i think 0-20 would be a good idea. just wanted to know what you guys think. let me know?

Actually Honda put out a TSB (Technical Service Bullitin) that all 99+ Honda Civic (except all Si models) switch over to 0w-20. Due to the extreame close tolerances of thier motors they will benefit from a lighter oil. This in turn will increase full economy without causing any damage to your valvetrain.
Heavier oils are recommended when your car begins to consume oil. In other words parts of your valvetrain are becoming so worn that they are letting oil pass through areas that they normally wouldnt. PLaces such as the pistons rings and valve seals. This is primarily due to high milage. 150,000+ miles.
It is perfectly fine to switch over tot he lighter oil. You may find yourself driving a bit further on your next tank of gas.
Now if you start to notice that your exhaust is emitting a blueish color then you will want to step back to your 5w-20 or 5w-30. Step up the weight until you notice that the blueinh tone is no longer present. However if you continue to see the blueish tone in your exhaust smoke then you may want to relook at your milage. If your up there in the miles then it may be time for either a new car or a rebuild.
I have a 2000 Honda Civic Si and I have always used Mobil 1 Synthetic 5w-30. I just clocked over 100,000 miles and have no blue smoke.
Also if the above mentioned conditions are presetn and you are low on the odometer then you may want to relook into your preventive maintance. Drive neglect is the leading cause of problems in peoples cars.
Note: If you notice white smoke then you have coolant leaking into the combustion chamber. "
