Will mixing synthetic with conventional oil cause a gel to form?
“I mixed Mobil 1™ with regular motor oil. My mechanic told me I should not do this because it forms a gel; is this true? I did it on three Honda Accords – a 2003 with 40,000 miles, a 1990 with 201,000 miles and a 1992 with 190,000 miles.”
