1. Shell Rotella T5 15W-40 Synthetic Blend

A synthetic blend oil with extra zinc and phosphorus (ZDDP) content, making it excellent for protecting flat-tappet camshafts often found in older Chevy 350 engines. It provides strong film strength, great wear protection, and keeps the engine clean under tough conditions.

2. Valvoline VR1 Racing Full Synthetic 20W-50

A racing-grade synthetic oil with a high-zinc additive package designed to protect classic and performance engines. It’s ideal for mildly or heavily built small-block Chevys that run hotter or under higher stress, delivering excellent anti-wear protection and stability.

3. Valvoline VR1 10W-30 Conventional

A conventional oil enriched with high ZDDP levels, making it a reliable choice for stock or mildly modified Chevy 350 engines. It balances wear protection and viscosity for older engines while ensuring smoother operation and longer life.

Recommended Oil Types:

10W-30 Conventional Oil – Commonly used in older engines; provides reliable lubrication in moderate climates.
10W-30 Synthetic Blend – Offers better protection and stability, especially for engines with higher mileage.
15W-40 or 20W-50 – Often recommended for high-performance or heavy-duty 350 engines, particularly in hot climates.
5W-30 Synthetic Oil – Provides excellent cold-start protection and is suitable for modernized or rebuilt engines.

If your Chevy 350 is rebuilt with tighter tolerances, synthetic oils may provide superior protection. For classic, unrestored engines, conventional oil with zinc additives (ZDDP) is often preferred to protect flat tappet camshafts.

Why Oil Capacity Matters

Engine oil plays a critical role in keeping your Chevy 350 performing at its best. Oil lubricates the moving parts, reduces friction, and prevents overheating. Too little oil can cause increased wear and potential engine damage, while too much oil can lead to foaming, loss of lubrication, and increased pressure inside the crankcase.

Maintaining the correct oil level ensures:

Optimal lubrication for longevity.
Better fuel efficiency.
Reduced risk of engine overheating.
Improved overall performance.

Oil Change Interval for a Chevy 350

The typical oil change interval for a Chevy 350 is every 3,000 miles or 3 months when using conventional oil. With synthetic oil, you may extend the interval to 5,000–7,500 miles, depending on driving conditions.

For older or classic vehicles that aren’t daily drivers, it’s still recommended to change the oil at least once a year, even if mileage is low, to prevent contamination and sludge buildup.

Signs You Need an Oil Change

Even if you keep track of mileage, it’s important to recognize when your Chevy 350 may need an oil change sooner. Watch for these warning signs:

Dark or dirty oil on the dipstick.
Oil pressure warning light.
Knocking or ticking noises from the engine.
Reduced engine performance.
Burning oil smell from the exhaust.

Tips for Changing Oil in a Chevy 350

If you’re planning a DIY oil change, here are some quick tips:

Warm up the engine – Let the engine run for a few minutes to thin the oil, making it easier to drain.
Use the right filter – Always replace the oil filter during an oil change. A high-quality filter ensures proper filtration.
Check the dipstick after refilling – Add oil gradually and check levels to avoid overfilling.
Inspect for leaks – Check around the oil pan gasket, filter, and drain plug for leaks after filling.
Dispose of old oil properly – Take used oil to a recycling facility or auto parts store.
