'''Introduction'''<br>
Thinner oil decreases internal resistance that the engine must overcome. This leaves you with a bit better fuel economy and power. 

== Instructions for mod ==
Look up the oil viscosities and temperature list for your engine. It can be found in your vehicle owners manual or on the internet. 
The thinnest oils will likely be full synthetic or synthetic blend.
Ensure the correct oil filter is used when changing oil.
Replace the plastic washer on your oil drain plug (if equipped). Do not cross thread or over tighten the oil drain plug.
Lastly refill your engine with the proper number of quarts or litres, recheck the oil level after the vehicle has been ran and left over night.
