1. If you're using 20/W50 oil, that's already about as thick an oil as anyone might want to use on these cars (and is probably decreasing your engine's performance slightly becasue it's so thick)...so moving to a thicker oil to further "mask" whatever problems the engine has developed would be detrimental...
2. You use whatever oil you want, I am not your father!! :)
3. All I meant about the oil weight I use was that if I'm using 5W30 synthetic and I'm not hearing pinging, then maybe you should be worried about more than how to quiet the pinging with oil weight...I might instead be concerned about WHAT'S causing the pinging and how extensive is it? Noise like that can only cause damage...
4. No grief meant to you...I just hate to see an approach that only masks the sound of a problem that will only get worse...
Best of luck...maybe try getting a trusted independent to listen to it and get his/her 2 cent's worth....
