I for one used Syntec 10/30 in my truck for 135000 mi and it ran great never used any oil. So why would I want to buy 10/40 with more polymers.The 5000 OCI works great. I thought about using M1 in my new car or Amsoil 10/30. So I will try 1 OC and test at 5000 with Blackstone. I have about 4000 on my 10/30 Syntec now will drain and test in another 1000.It liked mt Nissan truck so it should really like my SE-R.
Drew99, how did come up with this question?quote:
"Do you guys know if the 5w-40 has had sludging issues similar to the 0w-30?"
