Lucas Oil additives

  • Engine noise:

I use it in my Cadillac. It’s got the 3.6 vvt with the 3 timing chains. The motors like to rattle on startup even when there’s nothing wrong with the motor. No correlation codes no misfires. When I add this it quiets down considerably.

Pros: quiets down considerably

LIQUI MOLY Oil additives

What made the biggest difference was an oil additive. I usually regard those things as "snake oil," but this is a Liqui Moly product, so I decided to give it a go. It's called ViscoPlus for Oil. At one point, I only burned one quart in 1000 miles, a significant improvement over 1 in every 500 miles. The last go-round with Viscoplus it was somewhere around 750-800 miles before I had to add a quart. I highly recommend the Viscoplus.

Pros: significant improvement
Cons: effect varies

  • Smoke:

I had a cheap Volvo S40 commuter with bad valve stem seals back in 2011. I was about to tear into the engine, when a trusted friend/parts manager/guru recommended I try a can of Liqui Moly Motor Oil Saver as a last ditch effort. Within a couple drives the symptoms were gone, and last I heard the car is still running strong today.

Pros: symptoms were gone, car still running strong
Vehicle: Volvo S40

  • Engine noise:

I'm using Castrol Edge (or whatever) full synthetic 5w40 + about 250mL of Lucas engine oil additive (that stuff has done amazing things for other high-mileage engines I've had in the past).

Pros: amazing results, high mileage
Vehicle: Volkswagen Golf
