has anyone tried the Milesyn 05 w 20 oil as yet its full sync detros 1 and amazon cheap. Might have to try a case if its good, awaiting answers. THANKS

 

Why not just use Motorcraft 5-20 blend that Ford recommends. It's at Walmart at a good price.

 

Milesyn is a branded oil made by Reliance Fluid Technologies out of Niagara Falls, NY. Here's the rough specs on it 0w-20

Kinematic viscosity- 8.3.....a little to the thin side

Viscosity Index- 170.....good range

Noack- 13%...pretty weak for a synthetic

HT/HS rating- 2.6....absolutely the lowest it can go and still stay in grade. Higher is better. 2.8= average bearing wear.

Phosphorous- 850....decent

Zinc- 700 ....decent

I see nothing remarkable here except I wouldn't expect anything out of it that I couldn't get out of a much cheaper blend. Some of the blends will beat this in NOACK. Reliance makes other brands such as Fleetguard, Mach 2, Maxximum Performance, RFT, Sonic, Tuxton, and Supreme. A couple of these have had issues not being to grade and failed testing at PQIA, if you just want to search for it. Reliance is an API Certified blender but I found NO Ford certifications on any of it. They are a DEXOS Certified maker. Like I've always said here, if you pay for a premium product, you should get premium results. You won't find it here. This is available at Walmart and pricing is over that of better blends. YMMV.

 

Thanks for the reply I don't understand most what is Noack and If I may another question-If I change oil next time and use all mobil1 advanced at 3 qts 10w30 and 1qt of 5w30 then 3 qts of 5w20 would that be like using a 7w26 weight of oil ???? I'm not sure of all 10w30 the forum kinda mixes me up... I'm so old I remember being asked detergent or non detergent and re-refined (.15 cents) or standard oil (35 cents) THANKS Dallas

 

Do not mix brands, types, or weights of oil.

If you are talking about a Ford engine, use Motorcraft 5w20 synthetic blend or another quality brand of 5w20. Even though it costs twice as much as Motorcraft, I use Mobil 1 EP because I use extended drain intervals. I also use a premium filter - Mobil 1 or K&N. For standard drain intervals, a Motorcraft filter is as good as any.

 

From Wiki:
The NOACK Volatility Test, otherwise known as ASTM D-5800, determines the evaporation loss of lubricants in high-temperature service.[1] The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions.

The ASTM test heats to the oil to 250C or 482F for 1 hour. What cooks off or evaporates is represented as a percentage of the weight of the oil lost. So if an oil has a NOACK of 12, that means that during the one hour test, the oil lost 12% of it's weight due to the high heat and evaporation. NOACK is a MAJOR concern for those with turbo engines as they build tremendous internal heat. API and ILSAC says that a motor oil can only lose up to a maximum 15% or it fails testing and cannot wear the API certs.

The problem with mixing different oils together is you don't know what is in the formulation. Motor oil formulations are a highly balanced chemistry. Mixing will throw the chemistry off. It may not matter but then it could be catastrophic. That's the issue, you don't know.

 

Thanks to all you guys that have tried to help, I really mean THANKS this 5.4 has me awake nights worrying if its going to strand the wife and I sometime somewhere. I keep trying.. Again THANKS Dallas

 

Anyone else having trouble finding the Motorcraft Synthetic Blend Motor Oil, 5W20, 5 qt jugs? The price went way up at Amazn and Walmart is out of stock.

 

Have you tried parts stores?

 

Yes, I ended up finding it for 25.99 @ Auto Z.

Last year it was 17.97 free ship and no sales tax through Amazon. I wonder if the availability has changed?

 

Sounds overpriced to me. "Synthetic" can be bought for the same or less at walmart.

 

Sometimes Wal-Mart has a hard time keeping it in stock. I always keep enough at home for my next oil change and watch for it again to be in stock before I need it. Good luck.

 

That's probably what I need to do. I don't go to WM very often, I will admit I just checked if it was in stock at the website.

Thanks guys.

 

It's in stock at all the Walmart Supercenters around here for $18.53. Install the Walmart app on your phone to find it.

 

Amazon has 5 gallon buckets for about $50. Roughly $10 per gallon, or $2.50 per quart. How are you going to use a 5 gallon bucket of oil? Do you have that many cars to do oil changes all at once? Or will you open the bucket, use what you need, then save the rest of the bucket for later?
