She said that she had lived in Valdez (I think it is called) Alaska.
Some people here have worried about MMO thinning out the oil too much. But I figure it will not matter too much in the wintertime.
I have been using Pennzoil Ultra. There are some people saying that Walmart may stop carrying it. I am thinking about just going back to Pennzoil conventional. It is still supposed to keep the engine clean and I like to change the oil often anyway. A 5 quart container of the Pennzoil conventional is only about $12.00 or so at Walmart.
I still have a 5 quart bottle of Mobil 1 HM 5W30. I ran the Pennzoil Ultra for quite a while and it got cool and I think the Mobil 1 HM is a thicker oil. So I will save it for next summer.
CO is one beautiful state Mystic! You won't go wrong with PYB, I used is exclusively in many vehicles over the years. Used as directed MMO isn't going to thin your oil much. For those who worry a few things come to mind. Use a pint for the last 1000 miles of the OCI, or go up a grade in viscosity, or my favorite, use it for a winter cleaning. It gets cold enough where you live for you to benefit from the easier starts. I live on Long Island, have a Bitog buddy in MD we can tell a difference in cold starts with it. You'll see for yourself if you use it this winter.

LOL lets not even go there, its been quiet here, the shills are gone! More frequent oil changes will clean and protect far better than a 50,000 mile OCI on the "miracle' stuff for sure, and certainly keep an engine cleaner. The only way to keep an engine clean is to get the contaminants out, letting them sit in the sump and circulate doesn't do an engine any good.
