Lucas oil stabilizer is nothing more than 60w oil. I wouldn't put it in my Mustang or Lightning. Stick with a full synthetic oil.
Prove that statement.
Variable valve timing is why I'd stay away from it. There are tiny orifices that can get plugged by additives. NMRA guys use it and benefit from it because clearances aren't as tight as a production motor.
As a side note, companies spend A LOT on advertising. Just look at the "Tornado".
Yeah, because you see so many advertisements for Lucas Synthetic Oil Stabilizer, SOS for short.
I've run this stuff in all my engines. Here's a break down of some REAL WORLD experience.
1995 Dodge Ram 5.9L 4x4: These trucks were well known for shitting their transmissions at 60k miles and developing compression problems and oil leaks at 80k or so. I bought the truck with 65k miles on it. The transmission was acting up and the engine ran fine. I started with full fluid and filter changes on every component with oil in it. Refilled everything with quality fluids and added Lucas to the auto transmission and engine. I sold the truck with 125k miles on it and the new owner has the clock up to 175k miles in the year he has owned it. He hauls a 4500lb work trailer with the truck every time he drives it as it's his work truck. He has kept up the oil changes and using Lucas. That damned Dodge Ram still runs like a top. No other work done to it besides using Lucas.
2009 Honda Civic SI: From the first oil change, I used Lucas SOS. In the motor and the manual trans. When I got rid of it for my Mustang, it had 35k miles on it and ran awesome. The new owner lives in PCB and is a Pharmaceutical Representative. He has put another 90k hard miles on it. Still runs like a champ and he has used the Lucas oil as well.
2004 Chevy Trailblazer: We bought it new. From the first oil change, the engine and transmission both had SOS in them. That Trailblazer had 75k on it when I sold it. Last time I saw it, the lady had it up to 235k miles and it was still running strong. She says she uses the Lucas when her husband changes the oil.
1999 Mazda 626: Not known as a very dependable engine trans over 75k miles. We bought it new. I used Lucas in it from the first oil change in the engine and auto trans. When I handed it over to my daughter to drive, it had 110k miles on it. When we decided she needed a newer car since her college was five hours away, we sold that car with 235k miles on it. The engine and trans worked great. It didn't smoke, shifted great.....a *little* slip going into overdrive @ 90mph if you were flooring it, but everything else was falling apart on it. Had an oil leak from the rear main seal, Suspension, exhaust, A/C died, only one power window worked, kept warping rotors and eating through front pads, electrical gremlins in multiple places, rear tires wore out fast, etc. Drivetrain wise, it was solid as a rock. Have not seen it since it was sold.
I bought a factory rebuilt McCullough 18" chainsaw in 1994. It still works great to this day. Ran Lucas through it in every other 1-Gallon of gas. That chainsaw withstood HEAVY duty usage in multiple storms, while clearing land for my dad's new house before he died and after the tornado in Enterprise, AL in 2007.
Every single engine, vehicle wise or yard wise, that I've used Lucas products in is still running to this day. The Mazda 626 being the only one I haven't seen, but was running very good the day I sold it. And my daughter once spent 8 months away from home at Military college without my being able to check the car out. On her way home, the engine just died at a stop light about 110 miles away. I get there and check things out and guess what? It's completely dry of engine oil. The engine had seized up. I fill it up with oil, remove the plugs and it won't turn over. I get my 3/4" drive breaker bar and, IIRC, 24mm socket out and turn the crank via the crank bolt. Get back in the car and it turns over. Put the plugs back in and she is driving it home. The car had 170+k miles on it when this happened and she ended up putting more than 50k more miles on it before we replaced her car.
2011 Mustang GT: Has had SOS in it from oil change #1 in both the engine and transmission. 20k miles and no issues with the Variable Valve setup.
So talk shit and make WAIA's (Wild Ass Ignorant Assumptions) about a product you've no experience using. That makes you such an Internet Scholar doesn't it?
It's helped tremendously with blowby in that engine and it doesn't sound like a metal drum with BBs banging around in it on startup any more.
