Schaeffer's 6530 SynShield All Performance Synthetic Gasoline Engine Oil 5W-30 (5 Gallons) 

Schaeffer's 6530 SynShield® All Performance is built on a unique combination of select synthetic base fluids, an advanced additive package, and a highly shear-stable viscosity index improver — purpose-engineered for modern gasoline engines including turbocharged, supercharged, and direct-injection applications.

Two proprietary friction modifiers — Micron Moly® and Penetro® — protect metal surfaces at startup and during shock loading, delivering measurably superior results vs. API and GM benchmarks.

What you get with every oil change:

• 48% less engine wear on valvetrain components vs. industry limits — your valves and cams last longer
• 37% better timing chain protection — prevents the stretching that causes engine noise and timing problems
• 29% better overall wear protection vs. API and GM benchmarks
• Superior LSPI protection — guards against pre-ignition that can crack pistons, especially in turbocharged engines
• Cleaner engine — resists the sludge and varnish that accumulate with lower-quality oils
• Fewer top-offs — reduces oil consumption between changes
• Better gas mileage — friction reducers lower internal engine drag
• Ethanol-fuel compatibility — reduces the corrosion and deposit issues caused by E10 and E15 fuels

SynShield® All Performance Full Synthetic SAE 5W-30 is formulated for use in the following applications: 

API Service Classification SQ, Resource Conserving; ILSAC GF-7A; MIL-PRF-46152E; CID A-A-52039B; Ford WSS-M2C946-A, WSS-M2C946-B1, WSS-M2C929-A, WSS-M2C929-B1 and WSS-M2C961-A1; GM dexos1® Gen3*; General Motors 6094M; Chrysler MS-6395 and MS-9214; Toyota and Honda Service Fill Specifications; and Honda/Acura HTO-06.
