What does the ‘viscosity’ of an oil mean?

Viscosity is a measure of the thickness of an oil. The viscosity of the oil at low and high temperatures is measured on a scale determined by the Society of Automotive Engineers and given a number known as the SAE number. The higher the SAE number, the thicker oil. Therefore an SAE 30 oil will be thinner than an SAE 40.

What is meant by multigrade?

Multigrade oils were developed in the 1960

What is the difference between a mineral and synthetic oil?

Both types begin with crude oil. Mineral oil is obtained directly from the refining process, whereas synthetic oils are subjected to chemical processing which alters and improves its chemical structure. Synthetic oils therefore have better performance than mineral oils at higher and lower temperatures, but are inherently more expensive. 
As with mineral oils, there are differing levels of quality within the definition of synthetic oils, but the general advantages are:

Thought I had a flat battery, couldn’t move daughter’s car from outside the house. Rang Dave at Checkpoint, West Kirby to see if they sold the battery I needed. They did, but Dave would send someone down from Newhall, West Kirby to double check that is was in fact a new battery that was needed. Upshot is, car was taken to Newhall (seen and looked after by Billy), new battery fitted, programmed to car, and returned home within 2.5hrs. A competitive price too (no charge for car being diagnosed, taken away or brought back). Well done Checkpoint & Newhall....amazing service from start to finish. I will make sure I tell EVERYONE!

Have used this business over the last ten years at both their Mold and Queensferry branches. I find the staff extremely helpful and knowledgeable and have always found them to be very competitively priced, especially on servicing and tyres.

I have been a customer checkpoint for over 12 years.
I have always found the staff extremely polite and always manage to assist me with any issues i have.The products i have bought have always been top quality and if defects have happened, then the staff have been extremely apologetic and replaced them.
Thanks guys

Staff know what they are doing. Nice to have it all explained to me about what needs doing. Always 1st class service. Never need to wait longer than expected to get my car in, however small the job. If you are a woman then I do recommend this place for one reason only... I'm fed up being taken for a muppet by guys who just want to make their monthly targets.
Keep up the good work you guys.

Went to Checkpoint as I thought my headlight had failed on my estate. Agreed to get them to replace it . The person who came to replace the bulb for me used his experience and checked it first and found the bulb was OK just a loose connection. For this they said no charge. My wife has had a similar experience with them. Also we always find they provide good service and reasonable cost, this is why we use them.
