If I may, then differing brands of cars don't matter much? A Corvette ZR1 will perform about the same as a Toyota Corolla? A Ford Focus will ride as well as Cadillac? There's no difference in spark plugs, brakes, exhaust systems, tires, stereo systems, etc., etc., etc.? You know better than that. :) There's always differences amongst products, sometimes quite large differences.
 
Neither is RP , AMSOIL , MOBILE etc only Ford motorcraft is recommended

What I meant was that most new car companies specifically warn against the use of pour in oil additives and that using such products can void the warranty.

There isn't any oil named, "Mobile".

Any vehicle manufacturer always recommends their own parts and fluids, but of course. They get to take more money from the consumer this way. :)

Oils are recommended per performance ratings and many oils meet or exceed today's oil standards.
 
Don't mean to thread jack but I see a few people on here running 10w-30. Is that because of the weather you guys experience or for something else? I regularly experience 110 degree summers so I thought a thinner oil would help. If you guys have any opinions let me know.
 
I run Valvoline 20w50 Racing Oil.... non synthetic... In the SVT Focus, SVT Cobra, and its going into the Turbo 89 Lx as well.

That may of been what you ment but not what you said

DO WHAT ??? Wipe the amsoil from your eyes

Odd the local Chevy dealer is doing oil changes with Mobile in 2 WT you choose and filter for almost less then I can go to walmart and buy the oil and filter for 29.95

If this is the case why are we even having this discussion

If you like amsoil I say use it , If you like RP I say use it , I have NOT found any oil that will harm your engine and in the end that is the only thing that is important

I like Motorcraft Semi-Synthetic 5W/20, it is really good oil. O'Reilly's is running a special right now, 5 qts. plus a Motorcraft filter for $12.99
Its what I use and, ironically, what I was on my way to buy today. Thanks for the heads up on the deal-o!
 
Sir, with all due respect, your tone is very insulting, abrasive and condescending, as well as flaming. I really don't appreciate being treated like that. If you are going to nit-pick everything like this and be insulting, I don't feel this is very conducive to anyone learning anything. You don't know it all sir. A closed mind is a terrible thing to waste. Can we kindly knock off the unfriendly tone? Thank you.

Hi Slo. :) It all depends on what viscosity oil Ford recommends for your engine.
You will find this in the owners manual of your vehicle, or sometimes right on the oil fill hole cap. With newer vehicles, 10W-30 is not a very commonly recommended viscosity anymore. Usually the 5W-30 or 5W-20 is the recommended viscosity with newer vehicles.
 
i have never changed the oil in my car without a qt of lucas. ever since my 230k mi t-bird. had a rod knockin, put in some lucas, ran till 270k mi and motor still ran strong. just ended up rippin the rear out being stupid. come to think about it maybe i should have put lucas in the diff to!?!? lol i use lucas religiously. never heard anything bad ever happen from using it. plus i work at the dealer so... and the warranty was history forever ago n e way. you know like 90% of all those bolt ons can void the warranty to. so its safe to say i am the warranty now. lol but it really comes down to personal pref. so what ever floats your boat i guess.

How much of that semi-synthetic oil is actually synthetic oil? What's the percentage? Semi-synthetic, or blend oils, can have as little as 1% synthetic oil in them and still legally be called a, "semi-synthetic", or, "synthetic blend", oil. If the oil bottle doesn't tell you what the percentage of the blend is, buyer beware. Putting any petroleum oil into a synthetic oil only serves to reduce the performance and protection the synthetic oil offers. It's tantamount to pouring water into your favorite beer. "Yuck".

Consumer beware.
 
Any pour in oil additive I have ever seen in my 25 year automotive career are merely thicken the viscosity of the oil. Use a thick oil, like a 20W-50 and that rod knock also would have stopped. There's no magic. You could buy bulk 20W-50 oil, put it into oil bottles labelled, "The-Truth81 Magix Elixir Oil Additive", and sell it for a good profit I suppose. :)

Also, using any pour in oil additive will void the warranty with the oil being used in the engine. The point I was making with mentioning that many new car manufacturers stating using pour in oil additives is not recommended and can void the warranty, is that is not exactly an endorsement for pour in oil additives. Using any of these pour in oil additive products upsets the chemical balance of a motor oil that an oil company went to great lengths to formulate and can have negative and unplanned affects. If a cake recipe, (an oil formulation), called for 2 eggs, (additive chemicals in the oil), and we put in 2 more eggs to make the cake, "better", we'll end up with a cake, (oil), that isn't as good as what it originally was.

Using an oil that thick in a modern engine can cause the oil pump to fail, will reduce engine power, reduce throttle response, reduce fuel economy, increase emissions, increase engine wear, increase engine operating temperatures and shorten engine life. This is one of the worst things that could be done to an engine. Contact Ford Motor Company and Valvoline and they will tell you the same thing. Use the recommended oil viscosity for the best engine protection.

Here is an article for you that will provide a lot of information about oils -

I hope this helps.
 
like i said personal pref. you put in your thick oil and ill stick with lucas. and the fully synthetic type is not really much thicker than the 5w 20. i know the regular type is like straight tree sap. taking all of 10 min just to get a qt out of the bottle. lol
 
I guess you missed my point. The pour in oil additive IS thick oil. :) It's marketing bells and whistles. Don't be fooled.
