TR6 Oil and Fuel for TR6

Just a few months ago I heard about some fuel that had been developed from water and presentations had been made favorably to the US Congress. Now I hear the "perfect" Castrol GTX 20-50 oil is aggressively wearing out my camshaft all because the "sneaky" regulations required the removal of zinc from the oil. Because of the shortage of zinc in the oil, suitable and recommended oil for diesel engines should be used in my TR6!

Shortly after these announcements life goes on as if nothing has happened. Now you guys that had the camshaft ware out so quickly may know the real reason for the failure and it may have had nothing to do with the way it was manufactured.

Where is my water turned to fuel, and where is the zinc.

I am mad as heck and I want take it any more!

From Casrol

"
"Castrol is aware of articles in enthusiast magazines and web-sites, as
well as after-market parts manufacturer discussions concerning GF-4
engine oils and cam-shaft durability issues in older performance
vehicles. Some consumers suspect the lower level of ZDDP in GF-4 oils
may be causing these failures. Castrol is currently investigating this
issue.

For those consumers that wish not to use a GF-4 oil in these vehicles,
Castrol does offer the following products that contain Zinc at a level
that is higher than the Zinc level found in oils (API SG) marketed
during the "muscle car" era of time:
* Castrol GTX 20W-50 (SL,SM)
* Castrol GTX Diesel 15W-40 (CI4,CH4,CG4,CF4,CF,SL)
* Castrol GTX High Mileage 20W-50 (SL,SM)
* Castrol HD 30 (SL,SM)
* Castrol HD 40 (SL,SM)
* Castrol Syntec Blend Truck 15W-40
(CI4,CH4,CG4,CF4,CF,SL)(Semi-synthetic)
* Castrol Tection Extra 15W-40 (CI4Plus, CI4,CH4,CG4,CF4,SL)
* Castrol Hypuron S 15W-40 (CI4Plus,CH4,CG4,SL)(Semi-synthetic)

The following Castrol products have Zinc levels that are typical of API
SG oil:
* Castrol Syntec 5W-40 (SL,CF)(Synthetic)
* Castrol GO! 10W-40 Motorcycle Oil (SG)
* Castrol GO! 20W-50 Motorcycle Oil (SG)
* Castrol Grand Prix 4-Stroke Motorcycle Oil 10W-40 (SG)
* Castrol Grand Prix 4-Stroke Motorcycle Oil 20W-50 (SG)
* Castrol TWS Motorsport 10W-60 (SJ)(Synthetic)

If installing a new performance cam in an older performance vehicle, it
is important to:
* follow the installation recommendations provided by the cam
manufacturer
* use the recommended cam break-in lube
* prime the engine oil circuits
* use the recommended engine oil
* confirm valvetrain geometries prior to starting the engine with
the new cam

What I've figured from all of the dif site postings; Valvoline VR1 Racing 20w-50 carries a higher concentration of ZDDP (over the rec .10) and is still API rated for street use (proper detergents etc. not found in pure racing oils). Castrol 20w-50 has been cut to .075 or so.
Additives like STP and others that carry ZDDP could be used but some folks have experienced frothing because the additive(s) changes the oil chemical balance (particulary the anti frothing/foaming additive percentage). There is a web site that demonstrates this foaming issue using Castrol oil stabalizer in Castrol GTX.
I have no idea if STP, or other additives, would cause this same problem.
Many diesel rated oils have the additive package needed but diesels also carry more detergent due to the inherent ash in the fuel so may 'clean' an older engine more than you'd like if your tolerances are a bit off and carbon is assisting your margins. Also, the diesel oils will start reducing the zinc in the future to meet the same requirements.
Redline and other synthetics have the additives but some of us worry about increased leaks with synth.
I will now use the Valvoline VR1 Racing 20w-50 in place of Castrol.
Bottom line is become familiar with the additives/classifications and read the labels.
