Synthetic Gear Oils (with TGOA?) 
Description 
Castrol TribolTM 1510 Synthetic Gear Oils with the TGOA additive system represent a significant 
advancement in synthetic gear oil technology. Developed for service in enclosed gear drives, journals, 
and antifriction bearings, Tribol 1510 Synthetic Gear Oils are typically used where heavy shock load 
conditions prevail and operating temperatures are high. 
Tribol 1510 Synthetic Gear Oils are manufactured from synthetic hydrocarbon (SHC) base fluids 
(polyalphaolefin)., Blended into this fluid is the latest development in the field of surface improving 
additives designated TGOA. TGOA is an oil soluble additive package designed to reduce friction while 
providing surface protection and improvement. The TGOA additive package offers superior 
performance because of its unique action on frictional surfaces. 
TGOA works by establishing a highly protective metal rich lubricating film. This film is formed by the 
reaction of TGOA additives due to frictional heat and the catalytic action of metallic surfaces. The 
results are a smoothing of surface roughness without creating abrasion. Therefore, surface roughness 
is reduced without the usual loss of surface material. 
The results of the TGOA process can be compared with a rolling process in the micro-range. The 
surface roughness is gradually leveled and smoothed. Through this smoothing action, the actual loadbearing 
is enlarged with the loads being distributed over increasing areas. Therefore the actual load per 
unit of working area decreases. 
If the roughness peaks redevelop because of shock loads or stop-and-go operation, the TGOA additive 
package is automatically reactivated. Surface roughness is again smoothed and lubrication optimized. 
Tribol 1510’s have passed fourteen stages on the FZG Test Rig. Visual inspection after load stage 12 
showed gear tooth flanks like new. 
Application 
Typical applications are spur, helical, herringbone, bevel, and planetary gears operating at high 
temperatures. The continuous operating temperature range is from -300C to 900C with intermittent use 
to 950C. They are also used in geared couplings and where fine filtration is required. 
Tribol 1510 Synthetic Gear Oils may be used in antifriction and journal bearings. 
fill of the equipment. They have also been proven to be effective in applications where surfaces 
have previously been damaged in service. 
Advantages 
Because of TGOA抯 highly protective lubricating film the following advantages can be obtained: 
?Reduced friction 
?Reduced wear 
?Lower operation temperature 
?Lower noise level 
?Reduced pitting if not caused by design or heavy overloading 
As a result of the TGOA advantage the following benefits can be derived: 
?Longer gear and bearing life 
?Reduced maintenance costs 
?Greater productivity 
?High profitability 
Notes for Use 
Tribol 1510 Synthetic Gear Oils are compatible with petroleum oils and esters. This means that traces 
(up to 3%) of previous oil remaining in the gearcase after draining should not pose problems. However, 
the beneficial effects of the TGOA additives are reduced when 1510 Synthetic Gear Oils are mixed with 
other oils. 
Tribol 1510 Synthetic Gear Oils are not compatible with polyglycols. After draining a polyglycol fluid, the 
gearcase must be flushed well with a petroleum oil (flushing oil). 
A thorough cleaning of the gearbox is highly recommended to achieve the maximum benefits of Tribol 
1510 Synthetic Gear Oils.
