One quart of Royal Purple to see it on the stick?

Would adding one quart of Royal Purple at oil change time make it easier to check the oil level in an engine? I've never bought the stuff, but I'd pay a couple bucks more for a quart if it darkens the oil enough to make it easier to read on the stick.
 
No. The oil is purple until it is run in the engine, then the color disappears. Becomes light-gold colored after that like any other oil. Not worth it if this is your only goal with it.....
 
It loses its color fairly quickly. I don't know any tricks for the stick, other than looking on the back (usually smooth) side. Well, actually, the dipstick on one of my farm tractors was welded at one point and the heat turned it blue. I find it easier to rear than a light metal colored stick.

Its not very dark on the stick even when you first put it in, and within a day or so of driving it looks clear. Then it begins to soot up just like any other oil. I wouldn't think a single quart would do anything toward making the oil more visible on the stick.

I always look for the meniscus (curled edge) of the oil on the stick where surface tension makes itself visible. Wiping the stick with a rag and then waiting a minute or so before sticking it back down the tube helps make a clean line on the stick.
 
Thanks for the reply. It seems like oils are getting more clear. Mostly I use synthetics in about everything. Someone should sell an inert dye for oil.
 
Best way to check your oil that I have found is look on the back side of the dipstick where the metal is smooth. Hold it at an angle and it should be very easy to tell. Then you put your finger at the top and flip.
 
I find that I can usually see the new oil better on the stick when it's checked cold, even though that's not the preferred method I know...

I agree 100%.
 
The old trick of rough sandpapering the tip of the stick works. [clean it afterwrds!]

So will a pair of $3 reading glasses in a strong flavor.

You can always add UV leak-check dye to your oil.
