Well, I been studying oil for a long time, the weight of the oil misleads a lot of people, thinner is better. Most engine wear is upon startup, that is why we have a Oil Filter that prevents backflow, to keep oil at the ready for the start (Anti Drainback) Same reason lower viscosity number is better 5W will flow to moving parts a lot quicker than 10W will, a LOT quicker. Our engine is tight, you need a thin oil to fit into the tight places.
This is all layman's terms, don't make me get technical!

LUBRICANTS & FLUIDS
Engine Oil
Grade 1......API*
Series 2000 Synthetic 0W-30 Motor Oil
SAE 5W-30 Synthetic Motor Oil
SAE 5W-30 XL Synthetic Motor Oil
Above 0°F......10W-30, 10W-40
All Temps......5W-30[1]
Manual Transmission,.....GL-4
75W-85[2]
Notice the 0W 30W? This is popular in many race cars as of late. Can it be? yep! So no matter the weight so much as what it does. Odd eh? They been doing this to meet EPA requirements and get better MPG.

My wife's car uses this, 0W 20W (Honda Engine) The people at the shop freaked out about it, what do they know? Look at the drain interval, yes that reads a warranted 25K miles folks! Get that from Mobil 1?
New Energy Saving, Fuel Efficient AMSOIL 100% Synthetic 0W-20 Motor Oil
AMSOIL INC. of Superior, Wisconsin, has introduced a new energy saving, fuel efficient synthetic oil, AMSOIL 100% Synthetic 0W-20 Motor Oil. Several vehicle manufacturers, including Ford, Honda, DaimlerChrylser and Toyota, recommend either a 0W-20 or 5W-20 motor oil in many of the vehicles they produce, increasing demand for these oils. The new AMSOIL 100% Synthetic 0W-20 Motor Oil provides maximum protection in a light viscosity for up to
25,000 miles or one year, whichever comes first.
Product Description
AMSOIL 100% Synthetic 0W-20 Motor Oil delivers extraordinary lubrication for automotive gasoline engines. Formulated with the industry’s premier synthetic technology and additives in a light viscosity formulation, it withstands high temperatures and delivers outstanding fuel economy and cold temperature performance. AMSOIL Synthetic 0W-20 Motor Oil delivers long-lasting performance and protection, extending drain intervals far beyond those recommended for conventional oils. Its unique synthetic formulation and long drain additive system are very stable, resisting oxidation and neutralizing acids.
By delivering the best possible engine protection, cleanliness and performance over extended drain intervals, AMSOIL Synthetic 0W-20 Motor Oil reduces vehicle maintenance and waste oil disposal costs. AMSOIL Synthetic 0W-20 Motor Oil is designed to maximize energy efficiency for improved fuel economy. Its light viscosity properties reduce drag, while its uniform molecular structure helps it flow more freely to reduce friction between metal surfaces.
With its shear stable formulation and high viscosity index, AMSOIL Synthetic 0W-20 Motor Oil provides excellent viscosity film strength to separate metal surfaces and contains robust anti-wear additives for the best possible engine protection.
AMSOIL Synthetic 0W-20 Motor Oil resists thermal breakdown better than conventional oils. It is heavily fortified with detergent and dispersant additives to prevent sludge deposits and keep engines clean. And unlike conventional oils, AMSOIL Synthetic 0W-20 Motor Oil contains no wax. It stays fluid down to -65°F for improved cold temperature oil flow, reduced bearing wear and easier starting.
