Hey I work at a gas station and I just got my 8 about 3 weeks ago and already had to throw a quart in it. I knew I would have to but not this soon. So I went ahead and ordered some havoline 5w-30 so I can keep at the house and with me in the car. I also got a deal and it ended up only $2.60 a quart! What do you guys think of the brand with the RENISIS?
