In response to the author's article "Knowing which grade of motor oil to use in your car"
Good, safe information. Please allow me to add a few additional suggestions.
One, consider the climate and environment where you do most of your driving. For example if you live and operate your motor-vehicle mostly in Portland, Oregon in comparison to Miami, Florida you realize there are some extremely different conditions that will have an effect on the engine's operation. So if you operate in an extremely hot climate, you will want to use motor oils that are on the top of the SAE viscosity ratings which are approved for your particular vehicle. And obviously, if you operate in an extreme cold climate you will want the lower rating. Just for your information- SAE stands for society of automotive engineers.
Another consideration is one that usually won't affect most drivers. For those who have motorcycles you will want to know that there is a difference in the ingredients of motor- cycle oils verses automotive types. Most motorcycle oils have agents to reduce foaming. This is needed on engines which share the motor oil with the transmissions. This is usually the case with motorcycles. The transmissions stir up the oils in a violent motion way beyond what automobile engines do. Motorcycle oils usually are more expensive and most likely will not harm automotive engines; but automobile oils are not sufficient for most motorcycle engines. Always check with the manufacturer. When you speak to someone at the dealership about this, and if you get what seems to be vague answer, do not trust it. Seek higher up the skill level scale for an answer given with confidence.
Perhaps I should throw this one in as well for those who may operate a racing go-cart. Many of the racing engines on racing-carts operate at engine speeds above 20,000 RPM and beyond. I can assure you that off the shelf motor oils will not endure these speeds and your very expensive fast revving engine will turn those oils into smoke, and your fast revving engine will suddenly become a large paper-weight or boat anchor.
I know the subject was oil use in your car. But I thought it may be worth revealing some of the effects in other operations in addition to cars. Just in case we are one of those who assume too often.
If you would like further information about oils or other related subjects I would be happy to share my experience and knowledge with you.
