I am running synthetic Valvoline VR1 10w30 (street version) in weekend toy. I changed the oil 4.5 months ago and have not cranked since changing the oil due to schedule (0hrs/0miles). Since this oil is classified as racing oil, should I adhere to the 3 month oil life rule and change the oil, or can I extend the time on the oil. If I can what too? Not concerned with mileage on oil since I am not coming remotely close to hitting 3000 miles in a year let alone 3 months.
Thanks
