Hello,

My 2006 Ford F-150 King Ranch (5.4L V-8) just turned over 10K miles this week and I am in the middle of an oil change. This is my second oil change and both times I've used Motorcraft 5W-20 as recommended by Ford. A friend of mine has talked up Lucas Oil and swears by it, stating that it will add longevity to the motor. Yet I've read in other places that Ford doesn't recommend oil additives.

I drive my truck on weekends, so I don't put a lot of miles on it. My inclination is to not use Lucas in the truck just yet, but wait until it has 60 or 70K miles on the engine. Should I use Lucas Oil at all? If so, should I start now, or wait until the truck has more mileage?

 

Are you talking about Lucas motor oil, or their oil stabilizer? They make both, yet they are very different products...

If you're talking about their motor oil, then AFAIK it's not a well sought-after motor oil. I believe it is synthetic, but there are much better synthetics on the market today.

More than likely, you're talking about their oil stabilizer. I'd recommend not ever using it. This is solely based off the numerous discussion threads at www.bobistheoilguy.com. From what I gather, Lucas oil stabilizer contains absolutely no additives. All it is, is a super thick oil. But because it has no additives, it actually dilutes the additive package that your regular motor oil contains... When it comes to motor oils, additive packages are a GOOD thing (provided they're a good forumulation)... But of course, there's always a few people who swear by it. But within the motor oil "in the know" community, those people are far and few between.

 

Mucus, ehrrr, Lucas, is probably one of the most over rated lubricant companies around.

The motorcraft 5w20 blend will last longer than you may even own the truck.

I don't think there is such a thing as a "good" motor oil additive. I know Labnerd has recommended the Auto RX stuff, but I don't know much about it, and he seems to be very knowledgable, so I would consider it.

I'd also consider that Motor Latte stuff, since it has a long history without any problems. I checked into it with the manufacturer. It is allegedly a metal conditioner.

 

Theses motors havesuper close/tight tolerances. The motors were not designed around aadditives ergo dont use them. I can see the additives being beneficial in an older pushrod motor for lifters and what not. Definately not for overhead cam motors.

 

I've got 175,000 miles on my 5.4 and I've been using M1 5w30 since around 80k miles..... Mostly, just for peace of mind and my oil changes are between 5k-6k miles...

Never have added any kind of 'additive' to it and it just keeps on running.... Continue to tow the trailer in my sig all the time too...

Use a good quality oil & never use additives........

 

Thanks for all of your input. I was indeed referring to the oil additive, and it looks as though the general consensus is that staying away from additives (as Ford recommends) is the way to go.

I'll continue to use my regular oil selection and shy away from additives. Once again this list proves valuable!

 

Lucas oil ADDITIVE is nothing but an oil viscosity enhancer. You might as well put a heavier oil in from the beginning but expect the fuel mileage to drop and the internal heat go up. Lucas MOTOR OIL is pretty much a ho-hum formulation with the exception of a bunch of boron. Not hardly worth the asking price and the advantages are slim at best. Frankly, if this oil was free and Havoline was $3.00 a qt, I'd be using the Havoline. I'm not impressed with any of their products.
