Just watched a report on NBC News where Jiffy Lube is changing there 3,000 mile OCI recommendation to a more taylored per vrhicle OCI, considering climate, driving habits, manufactor recommendation, ect. .... The Jiffy Lube rep hinted at an average of 5,000 mile OCI with 10,000 being the longest... He said they would complete the changes by the end of the year.... They used Pennzoil during their demonstration.....
