Oil Change in Woodbridge, ON
Engine oil protects moving parts, carries away heat, and suspends tiny contaminants until the filter captures them. Over time, heat cycles and by-products weaken the oil’s film strength and reduce additive effectiveness. At Roy Foss Cadillac Woodbridge, we use manufacturer-approved oil and filters matched to your engine and driving pattern. Routine service supports smooth running, strong efficiency, and warranty compliance. Whether you drive a compact, a sedan, or an SUV, fresh oil preserves a quiet idle, crisp response, and long-term durability so your vehicle feels settled mile after mile.

When to Schedule Your Next Oil Change
The oil-life monitor adapts service intervals to real conditions, but many vehicles need an oil change every 8,000 to 12,000 kilometres. Signs include a service reminder, dark gritty oil on the dipstick, louder mechanical noise, or sluggish acceleration. Short trips in cold weather speed degradation because oil may not reach full temperature. Towing and heavy loads also raise heat and stress. Following the recommended schedule maintains reliability, protects the engine for the long term, and keeps ownership simple by aligning service with how you actually drive.

Oil Change Frequently Asked Questions

How often should I get an oil change?
Most Cadillac vehicles require an oil change every 8,000 to 12,000 kilometres, depending on driving conditions. The oil life monitor will notify you when service is due. Regular oil changes benefit vehicles of all types and ages by supporting engine longevity.
What are the benefits of regular oil changes?
Fresh oil improves engine lubrication, reduces friction, and helps maintain fuel economy. It also prevents sludge buildup that can lead to mechanical wear. In vehicles that lean towards performance, clean oil ensures the precise operation of performance features.
How long does an oil change take?
A standard oil change typically takes 30 to 45 minutes. This includes draining old oil, replacing the filter, and refilling with new oil. It may take slightly longer if your vehicle is due for additional inspections, such as the multi-point service the most complex models require.
What happens if I skip an oil change?
Delaying oil service can cause the oil to break down and lose its ability to protect the engine. Over time, this can lead to internal wear, reduced performance, and even engine failure. Timely oil changes are essential to preserving your Cadillac’s performance.
What about synthetic oil?
Cadillac recommends synthetic oil for most modern engines due to its high temperature resistance and extended service intervals. Today’s increasingly advanced vehicles often require full synthetic oil for optimal protection. Always follow your owner’s manual for oil type recommendations.
How do I know when my car needs an oil change?
Your oil life monitor will alert you when it’s time. You may also notice engine noise, a drop in fuel efficiency, or discoloured oil on the dipstick. If unsure, bring your vehicle to Roy Foss Cadillac Woodbridge for a quick oil condition check.
