Having problems with your 2008 Toyota Highlander ?

Is frequent oil change for Toyota Highlander bad for the engine?

\015 I have a 2008 Toyota Highlander and I change oil less than 3000 mi every 5 mos. which always comes first than my mileage. I only use my TH for long drive or freeway driving. Is it bad for the engine in the long term?\015 Posted / edited by AnonymousUser on : 01-06-2020

Answers :

It is good for your engine.

You have a good maintenance culture.

Cheers and rate this.
When I was younger I had a pontiac grand am 2.3L quad 4 engine with over 300k miles driven primarily on freeway over 150 mi per trip, it didn't smoke and had very little compression loss in the engine it lasted over twice the normal life of an equivalent vehicle it still ran fine when I got rid of it. That is the cheapest and best form of maintaining your vehicle I personally change mine between 2 to 3k miles and I own a mini van, work truck, and a luxury sports sedan. I would also recommend adding a quart of stp oil treatment at every oil change this helps to increase the amount of protection in your lubrication by providing an "extra cushion between your friction producing components as well as leaving your cylinders and pistons coated to prevent damage upon starting your vehicle when it has not been in use and all your oil has drained to the oil pan before it is circulated. This will add many thousands of miles to your vehicle life provided this as well as your other preventative measures are followed as recommended by the manufacturer/owner's manual. Glad your taking pride in your vehicle's condition so many othes do not.
