Has anyone got any feedback on this oil? I need to do an oil change this weekend and have heard from friends that this has worked well for them. I am kind of skeptical using a synthetic oil in my truck because I have no idea what the previous owner used. (conventional/synthetic weight etc.) The truck is a '94 22RE w/110k miles on it.

-TIA

 

i use it.....no problems, helps slow leaks for me alot.

 

Is there a legitimate reason why you shouldnt use syn after regular? Its highly possible im just ignorant about this, but I havent heard that before and def have changed back and forth in other vehicles.

 

no idea, all i know is the syn leaks through places the regular might not. and also I've heard that most wear on an engine occurs during the first 2500 miles....or somethin like that.

 

I have also heard this (synthetic leaking on high mileage gaskets) and thats exactly why I am skeptic of this oil. This is a full synthetic.

 

dont use maxlife synthetic, just regular maxlife.

 

Wasnt aware they had a non-synthetic version. Its funny, when I went on the Valvoline website they have a section where they tell you what oil is right for your vehicle and they told me I should be running maxlife synthetic.

 

Bob is right, use the regular Maxlife. My old Mazda started smoking like a SOB (worn rings) and I changed the oil with the Maxlife and 90% of cleared up.

 

thats proabably because its $4+ a quart, of course they would encourage it.....so would I to be honest. When I get around to rebuilding my engine, I might make the switch to snythetic.....I might even go back to non-maxlife for a while.....i don't know what goes into consideration about somethin like that.

 

I've been using Maxlife (non-synthetic) for a while now. No problems at all. 4Runner has 191,xxx miles on it, and runs great. Does have a few oil leaks, but that has been there since before I switch oils.

 

I am using regular maxlife right now. It's good stuff.

 

I am not too much of a fan of Valvoline, but Maxlife might be different. When I use to do my oil changes I loved my Castrol GTX.

 

Valvoline and Castrol is equivalent to Ford vs. Chevy........mostly comes from family tradition, and or personal preference. I'm sure that we could do a study on which one does better....but im not up for doing an experiment.

 

in that case, i wouldn't use either.

 

Well its decided then. Conventional maxlife for me

Now I just have to figure out what weight to run. I have a noticeable valvetrain chatter and have heard that heavier oils reduce the noise significantly.

What weights are you guys running?

 

arizona shouldnt get too cold, so 20-50 should be fine


however, heavier oil will just mask noise, valvetrain chatter can eventually lead to a engine failure and if its that bad, you need t ohave it fixed properly

 

Try this link ,it might help on your choices a little more.bob200587 is correct on "family traditon"I used havoline and fram,but now I use GTX and mobil 1 filter

Vehicles that leaked oil (high mileage) when I used Quacker State and Valvoline the vehicles actually leaked more oil that usual. When I switched to Castrol, the oil leaks slowed down rather actually.

But all the reason and experience comes through the senses which is all relative.

 

I'll be switching to MaxLife- what do you guys reccomend 10W40 or 15W40?
Thanks
