High mileage oil

Do you use high mileage oil and at what mile did you switch?

 

I don't use it and never will because plain old conventional got a bunch of my vehicles well over 200K. One made it to 415K.

Last time I read the label on one of these bottles it said something like "if your car has over 75,000 miles on it you should be using high mileage oil".

That's like telling a 25 yr. old it's time to sign up for medicare.

 

I think standard/conventional oil is just fine.

The major difference in "high mileage oil: is the addition of a seal conditioner that helps stop small oil leaks/drips. This is effective with older seals that have degraded in your engine.

Besides that there is really no difference. Sure they advertise all these detergent additives and extra lubricants, etc. But all major-brand conventional oils now have those same things standard.

A better consideration would be a switch to a partial (synthetic blend) or a full synthetic oil. Synthetic oils are different chemically and can be better for long distance/mileage driving and may provide better "cold start" protection to internal engine components.
