Option #1 is always do nothing
I would not increase the viscosity if your vehicle calls for less. The two work differently. The concept for higher viscosity is not to swell hardened gaskets/seals, but to only thicken oil so it does not leak as easily. This can cause other issues however. IMHO.My old Toyota 22RE is burning oil. 90% sure its valve seals though I don't have any smoke at startup no matter how long it sits. I'm going to be giving AT-205 a shot at the next oil change. Can't hurt to try. I'll probably mix it with some 10W-40 HM.
It is available at my local Advance Auto Parts for about $2 more than amazon.
Actually this may be a good idea. Alsoas many others said, high milage oils should be the first place to start, both because you get a formula that conditions the seals that is balanced by the manufacturer, but also because it does not really cost anymore than the regular oils anyways. Also bumping up the cold viscosity may decrease the leak. Persoanlly those three would be more first choices (tight bolts, high milage oil, a grade thicker oil). I have some reservations on Mobil 1 High Mileage oil, Valvoline or Pennzoil would be my go toBefore spending any money I would check and make sure all the pan and cover bolts are properly tightened, stopped many a leak just by tightening up finger tight bolts
12 bottles? Did somebody shoot a 50 bMG round through your engine block?I've had good results from red bottle Maxlife slowing/stopping a leak. Never had a mobil High Mileage slow/stop any leak either.
Try LiquiMoly Motor Oil Saver if you want an additive, works well too. Just snagged 12 bottles off Amazon for 20 bucks.
Nah, spreading them out every 2 or 3 oil changes over 3 vehicles12 bottles? Did somebody shoot a 50 bMG round through your engine block?
AT 205 is the best. Put a bottle in my 4 liter 24 year old jeep with a leaking rear main leak (I know it's shocking haha) and drove for about 4 hours and the leak has not reappeared since ( about 6 months ago).ATP 205...
I do not think I have ever ran anyting "High Millage" in anything. They just never struck me as anything special since we really have no idea what additives if any outside of what a $20 used oil analysis can detect has been changed. Now if every single brand told you what was tweaked so they told you specificly "30% more seal swelling agents" etc......It would make the sell easier for me. Most of them are just thicker version of their normal oil with slightly higher dose of AW additives as far as I can tell.I'd run a high mileage oil.
High Mileage oil is part marketing to higher mileage engines, but typically it is touted as more robust, and tweaked to condition seals in older engines. The oil companies unfortunately are not going to get too specific, if they did it would make life around Bitog easier for a lot of us.I do not think I have ever ran anyting "High Millage" in anything.

That said given how much I see it sell out in various brands I know a lot of people are using High Mileage products. The roads and parking spaces in Michigan look like a the Exxon Valdez was in town recently.
I generaly want my oil to be oil and my stop leak to be stop leak and my insert "speciliazed produce here" to be just that! Just like if I think my vechile has dirty injectors my first responce would be to get some Red Line SI-1 and toss in the tank not switch to Shell V-Power 98. Not that I am knocking Top-Tier gasoline. Good gasoline is about prevention not fixing a pre-exhisting situation. Does that make sense?
So I have always looked at High Mileage products as dubious at best like Synthetic-Blends. Even with SPAM I know what is in the can but not with High Mileage or synthetic blend! Cheers
