Motor Oils: Viscosity Ratings, Synthetic vs Conventional, and Engine Protection
Motor oil lubricates engine components, reduces friction, and protects against wear. Understanding oil specifications helps select appropriate motor oil for your vehicle.
Viscosity Explained
SAE ratings indicate flow characteristics.
5W-30, 0W-20, etc.
W = winter performance.
Second number = operating temperature viscosity.
Conventional Oil
Refined from crude oil.
Adequate for many vehicles.
Lower cost.
More frequent changes typically needed.
Synthetic Oil Benefits
Engineered molecular consistency.
Better temperature performance.
Extended drain intervals possible.
Higher cost justified for many uses.
Full Synthetic vs Blend
Full synthetic: all synthetic base.
Synthetic blend: mix with conventional.
Blend offers partial benefits at lower cost.
Full synthetic for maximum protection.
API and ILSAC Ratings
Certification of oil quality.
Current: API SP, ILSAC GF-6.
Backward compatible.
Look for current ratings.
Manufacturer Specifications

BMW, Mercedes, VW have specific specs.
Using wrong oil can void warranty.
Match manufacturer requirements.
Climate Considerations
Cold climates: lower W number.
Hot climates: appropriate operating viscosity.
Multi-grade oils cover range.
Match to your typical conditions.
Change Intervals
Conventional: 3,000-5,000 miles typical.
Synthetic: 7,500-15,000 miles possible.

Don't overpay for brand.
DIY vs Shop Changes
DIY saves money.

Oil change places use adequate products.
Practical Recommendations
For most modern vehicles, manufacturer-specified viscosity in quality synthetic ($25-40 for 5 qts).
Check owner's manual for required specifications before purchasing.
