Does Dexox1 Gen2 suppose to lower timing chain wear? Or just for LSPI?
GM has developed four new engine tests for this updated specification:
New General Motors Oxidation & Deposit Test (GMOD) verifies the improved oxidation and deposit control characteristics.
New Stochastic Pre-ignition Test verifies the added protection for turbocharged engines and pre-ignition concerns.
New Turbocharger Deposit Test verifies the added protection for turbocharged engines and minimizes deposit formation, which ensures optimal performance during engine life.
New Aeration Test (bubble control) ensures the air bubbles in the oil dissipate quickly to improve oil performance.
New Timing Chain wear (stretch) test.
It could be that oils were already good at timing chain and LSPI issues, but the dexos1 Gen2 tests prove
something to us.
