Conoco Philips, cleaning ability

[otis24]

I see that most (if not all) of Conoco-Philips products (TropArtic, Motorcraft, Kendall) all say resist sludge and varnish formation, but mention nothing about their product's ability to clean existing sludge/varnish.

At just over $2 per quart at Sam's Club, I will be using TropArtic in my beater car.

I wouldn't rely on them to clean much over a normall oil change. If you want to clean before using it try a mild engine cleaner such as amsoil engine flush or similar

Consistency is the key.
I feel that switching brands every oil change is the most effective way to keep an engine clean. The chemistries aren't the same and therefore the new oil will go after the old oils like an immune system on steroids.
None on my engines have any deposits anywhere following this mantra.
However there's a few members here using the exact same oil for decades and their engines are spotless too,so I'll say it again
Consistency is key.

I would say that any SN/GF-5 oil would be pretty darn good. The differences between their capabilities are likely dwarfed by the similarities.

I get Trop Artic cheap here as well, $1.99 a quart at a farm store. It's an excellent lube, I've even run it in the Jeep good stuff for sure. I am sitting on a couple cases and expect to run it in 3 of our 5 cars when the rest of the stash is gone.

IMO it is very typical of most oils, it won't leave deposits if you change at reasonable intervals, but don't expect it to clean much of anything up either. Cleaning existing grime with any oil is a very slow going proposition at best despite the marketing to the contrary.

you cant get that here in nj.... And everything else they make is pricey.
motorcraft used to be cheap but now its not so cheap

My 2005 Grand Caravan (purchased new) saw a steady diet of full synthetic motor oil. The last oil change was with Super Tech Full Synthetic. Now that the Grand Caravan has been relegated to the status of a second vehicle, I think I will continue to use the Trop Artic as long as I can get it that cheaply, as it is reportedly a 60 percent synthetic.

If you change the oil often enough, you will have a clean engine. I had an old car with a badly leaking oil pan. I was adding a quart every week. When I finally pulled the pan off, that crankshaft looked brand new.

Public Service Announcement:

If you ever buy a chrome plated oil pan for your car, make sure you sand the chrome off the gasket surface before installing it. Take in from me, I learned my lesson on that one.
