Ken, I entirely agree with you. If I was to purchase synthetic lubricant for a car that would be subjected to 30 below zero, I would buy the lower viscosity for sure. Anyway......................... Remember the car we are discussing will never be started when it is 30 below zero outside. It is leading a pampered life now compared to when I initially purchased it in 1972. So if I'm not going to start the car when it is colder out than let's say 32 degrees, I think it will be ok with the 20W50, would anyone agree?? I've used the block heater to prewarm the engine with 40W in it and the lifters didn't even tick because I would engage the starter and let it crank first for a bit and then set the choke and it would fire instantly and not clatter. thanks, Armand ----- Original Message ----- From: "Ken Ames" <ameskg@xxxxxxxxx> To: "AMC/Rambler owners, drivers and fans." <amc-list@xxxxxxxxxxxx> Sent: Sunday, March 22, 2009 12:27 PM Subject: Re: [Amc-list] Spring Flush > ...and the block heater doesn't heat the oil.
