This car was brought to me by a friend of a friend. It is owned by the original owner, IMMACULATE condition, never seen precipitation, original everything including tires and brakes!
Last time the oil was changed was 2015 which I kid you not was 1000kms ago. It was done by the local Toyota dealership.
He has expressed the desire to continue with conventional oil (5w-30) although he admits the length of time between oil changes was neglect on his part and vows not to do it again. We both (out of curiosity) decided to do a UOA just to see how it actually held up and if there's any notable wear to the motor. Problem is I don't know what the source oil is to be able to compare to the UAO. When he contacted the dealer with the part number from 2015, they responded that it is a bulk oil from esso that they "customize with their own additive formulation."
My two questions are: 1. Would it be useless to do a UOA if the VOA is unknown? And 2. What exactly do I tell him to use as a good conventional oil and OCI given the minimal road time it sees?
Thanks!
