quote:It's noticeable before the oil heats up, although I'm very easy on the gas during that time, but even more noticeable when it's finally hot. That's when the olde leafoote hammers down. It feels like I'm hauling three more people and a trunk full of luggage. Going by own rule of thumb, I must be losing somewhere close to 10 hp, or I wouldn't notice the difference. I'm just glad that you guys confirm my experience, so I can stop pinching myself. Anyway, this oil won't be in there for very long!
It's the 15W....that does the bogging...does it do it while warm?
