Too little and you have premature wear or worse.

The 20W-50 MIGHT make sense in some applications but certainly not for Boxster street use.

Hi,

All true. Too much viscosity and you don't have good flow. Also, heavier Oils create more Drag on the Crank, robbing Power.

15W-50 MB1 is what I use in the Esprit, but it has the much harsher Turbocharged environment to deal with, and it's a 23 y.o. car - the technologies and metalurgies were different then. And, 15W-50 is what the Manufacturer (Lotus) calls for...

Indeed, I am sure the Esprit can use every bit of viscosity in that bad boy!

Guys, Guys Guys...There have been plenty of discussions, testimonials, and studys on oil and its effects on a engine. Documented...Just look for the Oil Bible on the net and read what that study has found on numerous types of oil.

Really good information.

On a personal note, I use the Lucas additive in my 911, and have specifically noted the effects on the engine after adding it. I notied a noticable drop in oil temp, and increase in oil pressure, this could be from a more consistant viscosity, less foaming etc. But a definate drop in oil temp and that is crucial in a 2.7 motor.
SMOOTHER....absolutely...now as far a power goes, I will go as far as to say a better response, More power, probably not....even though the motor doesnt have to work as hard to turn the engine over, I dont think you would see a noticible difference. But definiately a quieter, smoother motor. Amsoil is about the same thing, the OIL BIBLE tells about it and other oils out there. Very good reading for when you are on the porcelean throne without an excellence mag...

The consenses is that most of these additives are not a bad thing, unless you are breaking in a new motor or a rebuilt one... But since most of us on this board are driving newer cars I will say that keeping a synthetic oil in your motor is very important.... And Mobil 1 is highly rated.

The Oil bible is a good doc but the last time I looked, a bit dated.

I have never seen anything that suggests that Lucas additive adds any value save testimonials.

Likely won't hurt or help but that is MHO.

Try Bob is the oil guy for a very good read on oils.

BRUCELEE....you just read my testamonial? Are you saying that I dont count

The stuff is great and I use 1 quart to every 5 quarts of oil..

but since I only hold 14 quarts in my car, I just use 2...
