I committed the cardinal sin of dirt bikes, I began working on my bike late Saturday evening, and now I need something and the shops are closed. Decided to change my oil and oil filter before the races tomorrow. I had one oil filter and one quart of oil. While leaning the bike over to get the last big of old oil to come out, I knocked over the open container of my new oil and lost half of it. The local shops are closed, and I need a quart of oil for my 08 YZ450F. Are there any suitable substitues I can get at a Pep Boys, Advanced, Wal-Mart etc. that won't harm my bike? Typically I only buy motorcycle specific motor oil, such as Bel Ray 4-stroke oil, so I have no expertise on other types of oil. HELP please !!
