It’s 7 qts 0w-20 synthetic only and the zero is equally as important especially on startup. If someone is going to buy oil it’s right there with the rest of it. In 2020 the manual shows no alternate weights like previous years.Its right at 7qts and yes you can use it and no it WONT affect your warranty
How many quarts of oil? And can I use 5w20? I bought the titan used and I didn’t receive owners manual.
