So, we all know about the potential for sludging on these engines if there is not a regular OCI.
My question: I have nursed my 2001 Toyota Solara 2.2 on Valvoline Durablend 5w30 since I bought it new. Now at 74,000 miles I am switching to Mobil 1 5w30.
Should I be worried about the potential for any previous sludge? Or was I safe in using Durablend all these years? It should be noted that I kept regular OCI's at 3500 to 4000 miles, with the Durablend.
