Infact
90 / 100
True United States

Changing engine oil every 3000 miles is a marketing strategy, not a technical standard. Jiffy Lube set standards for quick oil change centers in 1979, and Pennzoil owned Jiffy Lube by 1991. General Motors vehicles in 1978 had a 7500-mile oil change interval. The 3000-mile recommendation was based on severe service conditions.

Infact verdict: True (90/100).

The claim that changing engine oil every 3000 miles is a marketing trick is supported by multiple sources indicating that modern vehicles and oils allow for longer intervals, and the 3000-mile recommendation is outdated. Jiffy Lube's role in setting standards for quick oil change centers in 1979 is corroborated by several sources. Pennzoil's full ownership of Jiffy Lube by 1991 is confirmed by reliable sources. General Motors' 1978 oil change interval of 7500 miles is supported by historical documentation. The 3000-mile recommendation being based on severe service conditions is also supported by evidence indicating it applies to specific driving conditions.
