Regularly Check Your Car’s Oil to Keep it Running Well for Years

Oil maintenance and changes are just the facts of life as a car owner.

The shop has seen a larger number of engine replacements due to low oil damage this summer. These were engines with about 100,000 miles that were otherwise in good shape. When oil levels run very low, engine temperatures rise and the oil becomes sludge over time. Eventually that condition will damage or ruin the engine. We wanted to leave you with a few tips for staying ahead of low oil problems.

Recommendations Vary a Lot

Factory recommendations in your manual apply to a car during the life of its manufacturer’s warranty. They can suggest as much as 7,500 or 10,000 miles between oil changes.

Our own higher (75,000 or more) mileage cars and those outside the warranty receive an oil change every 3000 to 4000 miles (5000 -6000 miles when using full synthetic oil.) Maintaining older vehicles is very important to us.

Engines nearing 100,000 miles can go through 1 quart per 1,000 miles. This is called oil aspiration and is normal for an engine. When this happens, it’s possible to run out of oil between visits to an auto shop unless you check and top it off when needed.

How to Check My Car’s Oil

An easy, less-mess way to check oil levels is with a cold engine on a Saturday morning (or whenever you have a relaxed morning.) You are less likely to be rushed and the cold engine means the oil has completely settled. Pull your oil dipstick out and check that the oil is between high and low marks on the dipstick. No need to check after wiping the stick clean. You are checking the settled oil level. Make sure the car is parked on flat ground.

Many Dipsticks, One Idea

Engine oil dipsticks can come in many designs; remember to keep the oil level between the high and low marks whether that’s a line, hole, or label.

“I Want to Drive an American Car”

Many of our customers are rightfully proud of the American Automotive Industry and we occasionally hear from customers that they prefer American auto parts. As a veteran owned shop we completely understand that sentiment, but want to explain why the answer is complicated.

US Auto Parts Graphical Map

Let’s start at car models and work our way down to individual parts. What exactly should be considered in order to call a car American Made? This one paragraph from the Chicago Tribune illustrates the problem well.

…if you’re buying the redesigned S60 sedan. Volvo just opened its first plant in the U.S. on June 20 in Ridgeville, S.C. The Swedish brand owned by a Chinese multinational with an American factory invested $1.1 billion in the area just inland from the port city of Charleston. It makes the S60 and will employ up to 4,000 people to make the XC90 SUV in 2021.

Robert Duffer in the Chicago Tribune

A foreign brand, owned by a foreign company has a significant impact on the American economy, because of those employed in manufacturing the car here in the States. has created one way to evaluate a car’s impact on the American economy. They call it the American-Made Index.

The Jeep Cherokee ranks number one on’s 2018 American-Made Index and is manufactured nearby in Belvidere, Illinois. It contains 72% domestic auto parts. However, Honda ranks highest, as a company, with four cars listed in the top ten. Across all their brands, GM (which includes Chevrolet, Buick, Cadillac, and GMC brands) has the most vehicles that qualified for the index.

All the challenges of determining if a car model is American made are there when you ask the question about car parts. For instance, Toyo tires (a common new part here at Hi-Tech) is a tire manufactured here in the US by a Japanese company from rubber sourced out of south-east Asia and Brazil and synthetic rubber that is made from oil (a truly global raw material.) Unfortunately, there is no similar index of American made car parts to help us with this question. There are simply too many parts to have a comprehensive index.

Whether or not a car part is American made goes beyond the brand name on the package. High standards for quality and longevity of parts have always been important to our shop. The American auto industry is a big factor in that high standard and we are proud to be a small part of that industry.
