best synthetic oil and m/t oil??

[Hershey]

I used 5w-20 and 5w-30 Shell synthetic due to quieter engine , especially on interstate . That oil was less than $3 a quart . Also used Pennzoil Platinum at times . I think the Canadian tires Formula synthetic is SHELL . I've posted used oil analysises for the Yarises we had .

Yes, i've read that a few times as well, ct's formula syn is made by Shell. It's not a pure syn oil but the price is awesome on sale and my engine looks brand new inside so I'll stick with what seems to be working and is economical. Plus the winter start ups are much easier. Although i'm adding a block heater this summer.

Have you used or analyzed Mobil1 5W30 or Castrol Edge 5W30?
