Switch oil grades 5W30 to 10W30 after 90k?
Need some help here folks.
Any opinion on switching to synthetic 10W30 from synthetic 5W30 since my car is now in the 90k range. Does it need a higher viscosity since the engine has more miles on it or can I continue to use 5W30? The brand I use is Royal Purple.
