I know GC is near a 40wt when operating and this is what I wanted. The PP 5w-30 was being vaporized / burned more than the dino oil I used before, so I opted to try GC 0w-30 due to its hot thickness and the fact the engine works real hard once warm. When it sits all night outside under a cover, its alot harder to pull over now vs. the PP 5w-30. My ambient temps are 5 degrees to 30 degrees F. I would think the GC would be better for starting cold.
The engine is a tecumseh / ariens 6HP used on a snowblower. I had to rebuild the engine over the summer of 07' because it burned .5 qts per 30 minutes of use and made you sick after using it. The rings were shot and the piston was worn too small. A new standard piston kit and rod fixed it right up. I did however order 0.10" over rings and filed them to fit as a result of the cylinder being worn ever so slightly. However the engine still smells like its burning a little oil but uses .5 qt a month now which is great. Entire sump is 20 oz, so 1 sump a month is good enough for me as it is old and tired.
