Mobil SHC634 is an excellent gearbox lube. No questions. Expensive but these guys are about as good of a price as anyone. Ordered twice, the first container shipped and arrived within 2 days, super fast. The second time I ordered, I inquired after a week of no progress on the tracking number. Out of stock, not sure when it will be back??? It came in about another 10 days. Nice folks, just check stock prior to ordering if you need it quickly.
Easy to locate products and extremely fast order processing and shipment
Ordered online after failed extensive local search. Easy from start to finish and arrived ahead of schedule. Great company and will definitely order more products from PSC in the future!
