Hi folks, I just got my first Ford truck ever and I am getting attatched to it already; its kinda wierd. I have always been in Jap cars but got sick of having to take my latest car (Subaru) to the dealership for anything besides an oil change. So I got rid of it and got into a '95 4.9L 4x2. Its in need of some work but I do have a simple question. Has anyone out there tried Valvoline's MaxLife on their older engines? What do you think of it? I researched their website and they have testimonials claiming that using it stopped oil leaks. My truck has a leak and I wonder if this would be worth my while. I wonder if it really does condition the seals like they claim. Any advice?
Thanks
Maxlife and other high mileage oils generally have two things going for them. They are on the thick end of the viscosity range and they empoly ester technology to swell the seals. It may fix a small leak and it may not. Wear metals analysis I have seen on the web says it is a good oil and produces low wear metals. Give it a try, you certainly would be using a quality product.
I started using MaxLife almost two years ago, believing that it would stop or slow down the leak on the rear main seal. Didn't happen, in fact, the leak actually increased. Perhaps the Maxlife removed some sludge and allowed the leak to increase. Then again, perhaps the MaxLife had nothing to do with it and the leak just worsened on its own. Regardless, I think it is a good oil and continue to use it for its other qualities. At some point, I may have the rear main seal repaired, but right now, it is not so bad that I just monitor my oil and add a little if necessary. I haven't let the seal drive me crazy to have it repaired. Good oil is less expensive over the cost of the repair. Also, wife doesn't mind has I put lots of newspaper on the garage floor to catch any drips.
I am leaking from the oil pan gasket (easy fix) and rear main seal. I have a 95 4x2 4.9L.... any idea on how much I should expect to pay to replace my rear seal?
I have been told the seal is less than $20.00, however the labor could be in the high $300.00 range. Not sure of the complete accuracy of the cost, so perhaps some other members will jump in on this thread.

One of the ways these HM oils can work for seals is to clean them more so than an ordinary oil is capable of .
None of them are made the same though it seems but one constant is none of them work overnite .
I like the 10w-30 Citgo Ultra Life . Man , whatta oil . I also like the Mobil HM oil and the Castrol HM but for different reasons .
The topic Valvoline HM oil gets bad press on the internet because it does not have moly . Moly smoly , a good additive that does not make the world go round .
Valvoline knows what they are doing . I like the 10-20 percent PAO in it that they are using solely as a cold weather performance additive .
But the new SM Maxlife is listed to have 300 ppm moly, apparently to make up for the reduced zinc and phosphorus of GF-4. Still seems like it will be a decent oil.
All I used in my truck Is max life and a motor craft filter. The oil stays clean for a good amount of time it gets really dirty before the change at 3000 miles. Ive noticed that my rig uses less oil so far. It burned a half a quart now it burns 1/8 of a quart. Ive always like valvoline though. Its not really that much more than regular valvoline.

Just one of the differences between GF-3 and GF-4 is the latter has to be more resistant to oxidation . Moly was was used in GF-3 dino's as a primary anti-oxident and secondary anti-wear especially when used with group I oils " I posted a article here some time back " .
Without actually knowing if Valvoline has stopped using group I , I'll argue till the cows come home that the reason they now use moly according to the above post is they use cheaper group I and needed moly to help with oxidation and not anti-wear .
I guess we will see if this new generation oil is better or worse when analysis come in and if a new MSDS becomes available and this oil still shows some PAO in it.
Actually, I was hoping that GF-4 would force Valvoline into using better base oils, but since the cold properties don't look as good, I am starting to wonder if the PAO evaporated. I suppose one could get the SM Maxlife and throw in a quart of Mobil One for the PAO. But I think I will take advantage of the $1.99 sale at Pep Boys to stock another case of the SL Maxlife 10w30.
I just read an Amsoil testimonial the other day that a guy didn't change his oil for 400K miles and he took the engine apart and it was in brand new shape. Don't fall for the testimonials. In life you will always find extraordinary things. I've also read of guys living to be 120 years old who smoke and drink daily. I don't think that means we should all do it. Just stick to what works. Regular old oil that meets the specs your manufacturer requires and routine oil changes and maintenance. That's your best bet.

Yep several generations of that oil was made in a short period . One with moly for a very short time . Then one w/o PAO . Then the last with PAO that evidently was being used as a cold performance add more than anything .
Now the new oil with moly , some of the deal there is to aid with lowering of phos and zinc .
Search my user name here for High Mileage Oils and look at the adds in some VOA's of HM's Ive posted . The Citgo SL 10w-30 Ultralife looks like a racing oil Low cost too and does NOT use a seal swell agent . It operates with cleaning in mind like the Mobil HM . Both those HM's are recommended for newer engines too last I saw .
