I am ordering some Valvoline VR1 on Amazon since that's the cheapest I could find it. It comes in a 6 pack and the engine only takes 5. If I change the oil in the spring and in the fall, should the oil be good sitting in the house or garage for that long until it gets used? I am thinking so, but wanted to confirm it. Would it be better to store it in the garage or house or does it matter as long as it's not opened? Garage is attached, but unheated. Had a rough week with other stuff and brain is not working at full capacity at the moment.
