Hi,
for goodness sake don't tell Ted (Tooslick)you want to look inside M1, he will then want to "dismantle" M1 0w-40 to find out why millions of expensive high performance (hp/litre) and twin turbo/supercharged engines don't disintegrate when it shears? (actually Porsche, MB and AMG already know why and just won't tell Amsoil)
Now, another thought may be to also investigate why some Amsoil versions allegedly become more viscous - hello Ted!
Oh well, just a thought!!
Keep smiling - keep happy
Regards
Doug
