Containing a high detergent additive system, it helps cope with water, dust, dirt, and any other small deposits you might encounter on or off-road1. Pennzoil® Synchromesh Fluid also offers synchronizer compatibility for performance in manual transmissions, specifically to fulfill the needs of Chrysler, GM, Honda and other transmission requirements.

Pennzoil® Synchromesh Fluid meets General Motors specification 9985648 for use where GM part numbers 12345349 or 12345577 are called out for use. Chrysler manual transmission fluid specification MS-9224 is also met. This high quality manual transmission fluid is formulated for good low temperature flow to maintain shift characteristics even after a cold night2. Corrosion protection is added to help protect your transmission.

The Anglamol 6091 additive system contains approximately twice the sulfonate detergent levels as current generation PCMO, 4500 ppm as magnesium of magnesium sulfonate. This engine oil type additive will emulsify water and polar contamination sufficiently to handle contamination levels above 0.5% water.

Anglamol 6091 - Detergent, friction modifier, extreme pressure agent, seal swell, anti-wear, anti-oxidant.

Chemical Composition - Magnesium sulphonate, alkenyl amide, alkenyl ester sulphide, alkenyl phosphite, alkylbenzene, hecterocyclic ether, zinc dithiophosphate.

2 Pour point is less than -39°C. Low temperature viscosity in a -40°C Brookfield test of 50,000 cPs maximum, less than a 75W gear oil and the cold cranking viscosity less than a typical conventional SAE 5W engine oil.​​
