Best high mileage oil

[Eddie Lanham]

So I’ve been using a 10w-30 Pennzoil platinum high mileage oil (the one with the red lettering) for some time now, it’s been good to me. However I’m looking to put a thicker oil. I was thinking a 10w-40, I hear royal purple HPS(high performance) oil is great however my expedition is not a performance vehicle, just thinking maybe HPS oil will give it more lubrication. However they make a high mileage oil that costs 17 and change for One quart which is a bit much. Anyone have any experience with royal purple? I hear it’s good. Also does anyone have any suggestions?

-the reason for the switch in oil is I can hear a little bit of noise now, there’s no internal damage it’s just I’ve ran 10w-30 for a long time and I’m coming up on 205,000 miles driving from Florida to Mississippi. Figured thicker oil would add a bit more protection.

As always, thanks for any suggestions...

Also, not a fan of Quaker stake, Mobil, castroil, or valvoline. However I’m open to hearing anything

have you had an oil analysis done?

not sure thicker oil will make anything going on better per se' as any sludge build up is already there and if there are any occlusions to oil passages, perhaps make them worse.

a quick read, & sure others will chime in: https://thewirecutter.com/reviews/best-motor-oil-for-the-average-car/

These vehicles especially the 2005-2010 have oiling issues, due to a faulty oil pump, and small passages on the cam phasers that advance, and retard timing. If anything Ford recommends a much thinner oil. Your running too heavy an oil now. 5w30 is the heaviest grade you should run, along with a Ford or high quality filter. Amsoil is a top shelf synthetic, its one of the oldest ones around. Been around since early seventies. I run Mobil 1, and have been for going on 40k miles. I change mine way above recommendation to keep clean, around 5-6k intervals. You might want to stick with either the oil you've been using, or switch to a semi synthetic like Fords own. Oil is like tastes in women, some like blondes, me its brunettes, then theirs that crazy guy, that likes feisty red heads. I'd drop down to 5w30 though, don't go up. The ticking is unfortunately something you'll have to keep an ear on, and if it gets worse, then you might have to make a decision.

I wouldn't go thicker, but in terms of brands, you can't go wrong with RP imho. http://www.animegame.com/cars/Oil Tests.pdf
