Amsoil Signature Series 5w50 is really the ultimate for street and track. The cold flow is superior for start ups and really holds up well with the added raw fuel washdown and dilution all GDI engines experience. I think most assume as the owners manual states to use a very thin viscosity oil that it is best when that has nothing to do with proper protection and is only to allow the automaker to meet CAFE fuel economy standards for that vehicle the engine is in. GDI engines experience far more fuel forced past the rings do to a combination of the 11.5:1 compression ratio as well as the intense pressure the fuel is introduced at, 2,000-3,000 PSI. This combined with long change intervals is extremely hard on the bearings and journals as well as timing chains, tensioners and other internal parts. Then add the abrasive particulate matter shed from intake valve coking and your oil has never had to work harder to protect your engine.
Installing the Elite E2-X crankcase evacuation and air/oil separating system provides full time evacuation of these compounds as well as 95% plus reduction in the ingestion of these compounds. Consider this as well to aid in keeping the engine oil clean longer as well as reduction of KR caused by detonation.
You will also see less coking from using an ultra clean synthetic as it leaves almost no residue when burned.
