Just out of curiosity, how many people here use Valvoline maxlife synthetic blend, if so how long have you been using it? And what is your mileage? I have a 13 Ford Edge with a 3.5 I've been using 5W20 weight for the last few years I have about 113,000 MI, I just got a UOA back absolutely no metals, showing absolutely no signs of wear, and plenty of TBN left in the oil.
I currently have MaxLife in my Jeep 4.0L and somehow the engine isn't leaking and still full of oil, which is rare for a 4.0L. It did slow some of the seeping I had from the engine. Also currently using the MaxLife synthetic 5w30 in my dad's Grand Cherokee with the 5.7L.
When I had my 2008 Tacoma 4 cyl. At 60K it had a bit of weepage in several spot on the valve cover gaskets. Tried the 5w-20 Maxlife Blend, the weeping never got worse. Seemed to have worked. Continued using until I traded it at age 10. The 20w-50 cut the oil comsumption on my Old Beemer by 3/4. It had leaky pushrod tube seals and several others leaks here and there.
I started using it at 200,000 miles in my 2005 5.3 Chevy truck. Currently at 225,000 miles with no runs, drips or errors. Just ordered 3 five qt jugs 10w30 flavor from WOOT for $39.99 per a post here in the sale and rebate section with free shipping for Amazon Prime members….woot woot!
I used Valvoline Max life in my Acura TL years ago, I was doing 5,000 mile oil changes. I still would use it except there's better deals on oil so I switched to another brand oil....I never had any problems with Valvoline Max life 5w30.
