Hap et al,

I agree with folks who are not Walmart fans; however, if you do your own oil changes, you cannot beat their prices on quality motor oil.

BMW approved Castrol Edge Full Synthetic is sold at Walmart in a variety of viscosities for a very reasonable price. As has been noted previously, they also sell Mobil 1 in a wide range of viscosities as well; however, Mobil 1 lost their BMW approval a few years back. I still use it but for those of you who insist on BMW approved fluids, Mobil 1 no longer qualifies...

I currently am running Castrol Edge 5W-40 LL-01 approved oil from Walmart in my M235 with the Mann filters. I am an old school maintenance follower and since my M235 is my DD, it gets changed every 5000 miles even though my driving is about 90% highway and 100 miles a day. I change my oil every 10 weeks or so.

If I was still living in Upstate NY, I would likely have stuck with Mobil 1 0W-40 for the low temperature viscosity benefits with the turbocharged engine. Connecticut does not have the -20F mornings I experienced there so 5W-40 is fine.

My two cents...
