“I've used Castrol engine, and other, oils for over 60 years now and have always found them to perform well. I bought this for my 2007 MX5's annual service as I have done for all of the time i've had it since I started servicing it 3 years after I bought it, the oil looks as good when I drain it out as it does when I fill up to start with.”
“They do say, manufacturers recommend etc, but I have tried different oils over the years for my car and always come back to Castrol. The engine seems to run smoother and quieter with this oil and so would recommend this to anyone wanting decent oil”
“My engine has a mileage of 244500 and is still fine runs well still manages 48mpg and is a 2006 model. I've used Castrol Edge 0/30 and now 5/30 as it has a fair amount of miles on the engine. Never a problem.”
