here is a what turned out to be a very good thread about oil. check this out it may help https://www.nopistons.com/forums/index.php?...topic=50483&hl=

 

castrol GTX 20W50

I've been switching between that and Shell Rotella T which is 15W40.



I get them for 8.80 cdn for 4 litres that 6.98 for 4 litres. Sorry I'm not going to convert litres to gallons that is too difficult.

 

That Shell Rotella 15/40 is some good stuff. I've used it for years. S5TII. It's for diesel and gas applications for added protection. Years ago the Castrol 20/50 could be used for diesel or gas, but to save money they eliminated the additives to ensure the diesel application. It's only for gas now.
