Someone said they wanted more oil analysis' from less common companies (good idea). So here is an analysis of some Meijer brand full synthetic. At the time I purchased this (2017), the oil was made by "Warren Oil Company" which could be seen by the stamp on the plastic container. This will probably only be interesting to those in Michigan/Indiana(?) area. I know Meijer is not all across the US. Details: Meijer 0w20 Full Synthetic (Warren Oil Company) STP Maximum Life Oil Filter - 15k mile rating 2003 Ford Focus 2.0L Zetec w/150k miles OCI - 14,200 miles Mix of highway and city driving with 1 winter I was a bit disappointed they did not directly tell me to go more or less so can someone help me determine if I should go more or less miles on this oil? Can someone help interpret? They say "no trouble" but also say "aluminum was twice average."
