"The Petroleum Quality Institute of America conducted a study of 303 fluids purchased from store shelves at random in 2017/2018 in order to determine their performance levels. Their results were shocking to say the least:
"The Petroleum Quality Institute of America conducted a study of 303 fluids purchased from store shelves at random in 2017/2018 in order to determine their performance levels. Their results were shocking to say the least:
- 91% failed to meet the J20-C and J20-A specifications
- 74% failed to meet any JDM specifications
- 60% chance of lower anti-wear protection than J20-C
- 73% chance will offer less detergency than J20-C"
