Are they not referring to Max Life?


i think you have to take it at face value, don't use full syn if you have an oil leak


Ever hear of ATP AT-205 Re-Seal ?
that is the real deal!


Do you sell this stuff?
 
The blend is sufficient and has a good slug of synthetic in it, more than 5% I beleive. The specs are very similar to the full syn.
 
If you are experiencing leaks, stick with the semi-synthetic. The only advantage synthetic would give you is you would be leaking a more expensive oil.

Personally, I would just try the regular off the shelf Maxlife (blend). If that doesn't help, and you live in a warm climate, try the 10W30 weight. Once engine warms up it should flow as well as 5W30, but when the car is sitting in a garage it should be a little thicker than 5W30 hopefully reducing the leak.


My thoughts as well.

Does this mean most of the leaking occurs on startup or cool down as the car is sitting?
 
Leaks happen when the car is running, unless the leak is the drain plug. If you look at Valvoline's PDS sheets on red bottle vs. full syn MaxLife, there is not a lot of difference. Also, with the discontinuation (sp?) of DuraBlend, red bottle MaxLife is beefed up to meet/exceed GM Dexos specs-that's the way I go.
 
Thanks,man. I got some Mobil super HM ready to go,since I have been running M1,but,will try Maxlife red if the Super HM doesn't work. I agree that,the blend,is the way to go.
 
remember reading that blends are 30% max by rule no mininum, oil co.'s like to keep you guessing, even amsoil answered an e-mail with the propriety BULL as to what group oils they use in their different products. i do not think i will be paying their higher prices for a product like signature series when thet can't state in print what they use, as they now sell cheaper OE spec oil which valvoline synpower specs compare well, prolly my new choice and is a dexos I oil, they let you easily access their specs unlike others that seem to hide theirs

Not true. Pennzoil Synthetic Blend Dexos is at least 50% synthetic (from their website).
 
In the last few years I have tried to stop 2 different rear main seal leaks using M1 High Mileage. In both cases the results were nil - oil leak continued unabated - same as before. A friend with an old Camry had a rear main seal leak and I recommended regular Maxlife - it slowed down his leak considerably. IMO use semi-syn if you have a leak already and full synthetic if you're trying to prevent one in the future.

What's Valvoline synthetic's dexos1 license number? I don't see them on the dexos1 list and they don't claim dexos1 licensing on their website, and I haven't seen dexos1 logos on their bottles.
 
the 10w-xx cold temp pump test are the same for all oils , 10w-30 , 10w-40 must meet the same Dynamic Viscosity standard. Same is true for 0w , 5w , 10w , 15w , 20w, 25w .

Kinematic Viscosity 40 weight oil can have different High Temp High Shear rate.

0w-40, 5w-40 , 10w-40 , HT/HS > 2.9
15w-40 , 20w-40 , 25w-40 , HT/HS > 3.7

They all have the same Kinematic Viscosity of 40

One other question. I live in Los Angeles where it does not get very cold. If the 5-30 does not help, should I try the 10-30? Or, it is better to stay at 5-30 as recommended and use Bar's or something else for the seep.
Thanks


You can get it cheap at any NAPA auto parts store in your area, and if they do not have in stock they will have it in 1 hour. I was happy not to have to use AMAZON for this OIL.

I dunno why most places to not sell it like Walmart of Autozone, I asked the guy at NAPA and he says the only stock whats ordered and not picked up, for instance if someone orders 10 Quarts and it comes in 6QT boxes then the would stock 2 quarts on the shelf at the same price as say Mobil 1 or even less $.

So google napa and see if there is 1 nearby you .

That's a pretty cynical viewpoint: which blends are less the 5%? Of course, we don't know for sure the % of synthetic manufacturers put in blends, but Pennzoil Gold says on the bottle the syn portion is 50%, which is probably typical. Plus any blend that meets the Dexos1 spec has to have a pretty high syn percentage as well.




Its the first blend oil I have ever seen say that and you are correct however all the others I have read about do not say 50% and if they were 50% im sure they would state it like it does here... Good call buddy.
