Went to Walmart and even checked on Castrol's website. Looks like they discontinued GTX 5w-30 conventional oil. I called them and was told the same thing.
Anyways I don't change habits LOL unless there is an issue, and have been using this for every oil change since I bought by Silverado in 2002. Not once have I used anything else and I am at 160K miles. I guess Castrol Semi synthetic Ultra Clean is my next choice. I am not one to mix oils even though I know it wont hurt and I see people on here do it all the time.
I wonder why they discontinued this?
Thanks
