What We Like

This Castrol Synthetic motor oil has a viscosity that is probably one the product’s most invaluable features. Its ability to retain its thickness despite running for long ensures optimal engine performance regardless of the operating temperatures. As a result you can use the same oil in both high and low temperature conditions because it’s both snow & heat resistant. There’s absolutely no need to switch the oil to another brand as soon as the weather conditions change. For this sole reason, this makes it cost-effective.

Thanks to the Castrol Synthetic motor oil’s impressive protection properties, your vehicle’s engine is preserved for much longer. Other customers who’ve used it on vehicles with high mileage have reported that it significantly improved the overall performance. The oil even goes as far as minimizing certain problems such as piston slaps especially in cold weather resulting in quieter valves.

You’ll find that this oil tends to stick to the metal surfaces in your vehicle which is a good thing because it lubricates your engine continuously. Even after you leave your vehicle idle for an entire weekend, come Monday the initial start-up is pretty smooth—especially in cold weather.

What We Don’t Like

This isn’t the cheapest motor oil on the market. You can get a cheaper alternative elsewhere. What remains to be seen is if the cheaper brands are as effective as this Castor Synthetic motor oil.

We’ll also point that it’s not easily accessible in most brick and mortar stores so you may have to opt for online purchases. And even so a few users have experienced delayed deliveries upon ordering this oil. Some sites even explicitly state that delivery can be expected between one and two months. So, you might want to stock up when you get the chance.

A handful of customers did mention that they didn’t notice much improvement on their vehicles upon using this oil. Others even state that their cars began running sluggish especially after attempting high speeds. Our only advice to you in this regard is to check your vehicle manual to confirm if you can indeed use this oil for your car.

We’ll have to warn you that the tamper protection seal is rather tough, making it a little difficult to open. You’ll need to use a razor blade to pop it open. But we guess the manufacturer did this to ensure zero leakages while your package is being shipped.

FAQ:

How long does Castrol Full synthetic oil last?

Castrol full synthetic oil is estimated to protect your engine for 10,000 to 15,000 miles or six months. However, this may vary depending on various factors. Such factors include your driving habits.

For instance, the start and stop driving are not recommended. If you travel short distances, maybe from home to work and back, your oil may deteriorate fast. When you start up the engine, it takes time to heat up and warm the oil. For a start and stop driving, the engine is turned off before it heats up well.

Also, the miles covered by the synthetic oil depends on the driving conditions. There are a lot of rapid movements and shifts in a racing car engine. As such, the oil operates under extreme pressure and temperatures.

Before using it, Castrol synthetic oil can last up to 5 years in the bottle before expiring. Note: the storage time is subject to proper storage. It would be best if you stored it in a cool and dry place.

Can I use it on my 2011 BMW?

What you need to know is that BMWs are European engines. And this Castor brand is American oil. In our experience, this makes it too thin for Euro engines so you’ll need thicker oil. But to get the exact answer we highly recommend that you consult your user manual or visit your manufacturer’s website if you don’t have the literature with you.

What’s the difference between this oil and the same brand’s product that doesn’t mention “high miles”?

This means that this particular oil is specifically designed for vehicles with high mileage compared to newer cars. Ideally you must use this oil if your car has a mileage of over 75 000 miles. This is because it contains additional protection properties for such vehicles.

Can I use this Castor Synthetic Motor Oil in place of my conventional oil?

Because it’s synthetic oil, it’s safe to use in most vehicle engines plus it provides even better protection than conventional oils. But again, make sure you check with your car user manual if indeed this oil meets your vehicle oil requirements with regards to weight and thickness.
