Q: I’ve a restricted version 2008 Toyota Highlander V6 with 74,000 miles on it and it runs nice. I’ve been utilizing common oil because the automotive was new. Can I modify to artificial oil? Is there any profit to altering the oil at this stage of the automotive’s age? TRUE?

A: Artificial oils have the additional advantage of improved lubricity, which helps decrease chilly put on within the engine. Artificial oils additionally assist with chilly climate begins and are extra resistant to grease breakdown in sizzling climate.

As for switching, you may freely swap between artificial oil, semi-synthetic oil, and traditional oil with none issues.

I just lately had Pennzoil’s Michael Thomas on my radio present to speak about this very subject. The Automotive Physician podcast might be discovered at or most podcast websites.

Q: I’ve a 2008 Nissan Frontier V6 4X4 with a guide 6 pace transmission that simply hit 60,000 miles.

4 years and about 35,000 miles in the past the ABS mild got here on and 4 wheel drive was disabled. After diagnostics on the seller ($160) I used to be instructed the truck wanted an ABS actuator. Nevertheless, I used to be additionally instructed that this half will not be accessible within the US as a result of it’s a guide transmission.

After contacting Nissan (Tennessee), it took 6 weeks to search out Nissan North America or get the primary vendor to construct one. After spending $1,600 ($1,000 for him on elements and $600 for labor) the issue was fastened. Quick ahead 4 years and you will have the very same downside, and the identical downside together with your elements.

Nissan was capable of finding two ABS actuators. The truck is in nice form and I simply changed 4 tires with one other pile of cash.

Does this sound regular in a automobile like this? Any concepts or ought to I drive the truck for a couple of years and cross my fingers earlier than shopping for a brand new Toyota?

A: I think the standard of the substitute half was not so good as the unique. Consequently, their lifespans had been comparatively brief. The truck he is had for almost 15 years however has very low mileage so if it is structurally sound you may need to repair it up and drive it (some Nissans have severe rust issues). had issues).

$1,600 is dear, however it’s about three month-to-month automotive funds whenever you embrace the price of a brand new automotive.

Traditionally, Toyota merchandise have had much less issues than Nissan vans, however Toyota has additionally had rust and engine issues.

Q: I noticed an article about shedding air in tires. My spouse’s automotive had the identical downside. After the store checked a number of occasions over a number of months and added new tires and valve cores and caps, I used to be lastly capable of determine it out for myself. It took about quarter-hour earlier than it began to bubble. this would possibly assist another person.

A: Thanks for the ideas. Some outlets will rebuild the tire stress sensor whenever you change tires. This consists of new caps, valve cores and a rubber seal across the steel stem. Pre-tire radio frequency stress monitor, new valve stems put in on almost all new tires. A brand new valve stem solved lots of the tire leaks.

Q: My 2013 Nissan Rogue has about 73,000 miles on it. I modify oil recurrently. The automotive begins high-quality, however as soon as I take advantage of the automotive, I’ve to attend not less than 20 minutes or extra earlier than utilizing it once more. There’s a cranking sound, however it does not catch. After about 20 minutes it boots up and works high-quality. What may very well be mistaken?

A: The one you’re referring to is named a “sizzling soak”. Engine compression, gas and spark are wanted to run the engine. If any of this stuff are lacking, it won’t boot.

At this level, the very first thing to do is test the battery, cable connections, and grounds. Poor grounding, not supplying voltage to the ECM, may very well be the issue.

Different prospects embrace a defective crankshaft place sensor or an ECM (laptop) that’s being affected by warmth.

I like to recommend leaving it at a store so you may hook up check gear and check it after the engine is operating.
