Just don't put ideas into members here that ESP is more granduer than Mobil-1's 20k oils, for workplace, school kids hauling and shopping center activities. There are numerous members here that have used oils like Supertech and NAPA for 15-20 years. Heck,. right before Pep Boys closed their auto part stores, a BITOG member autoparts worker transported parts to businesses and homes, racking up over 360k, using nothing but Pep Boys house brand oil.
So really, how important is sub 10 NOACK, flashpoints that won't end the OCI over 400 - HTHS that never saw upwards of 2.9.....etc.....etc? To me it;s about engine cleanliness and engine wear protection - claiming no right to dismiss superb oils like Mobil-1 EP.
