I am looking to buy a used Honda Fit in my area. It's from a private party, original owner. When I asked him about service history, he told me he usually takes it to one of these quick lube shops for maintenance. I didn't even ask about the auto transmission service but I assume the same. I haven't been to one of those places in over 2 decades or so but from time to time I drive by one and see advertising stating they use this or that premium brand oil (e.g., Castrol). But the filter quality is most likely subpar unless it's also sold by a name brand like Pennzoil.
In any case, I won't be able to take the car to a mechanic for a PPI since the seller is about 40 miles from me. Should I be worried about the lube xpress that doesn't use quality oils for lack of additives? Assuming he did the oil changes (for which he says he has records), would this engine have extra wear due to low quality oils? Thanks.
Edit: As mentioned on the subject line, the car has 106,xxx miles.
