It’s lost power for sure, all engines do as they age.

 

I am quote familiar with the 4.3, I had it in my GS430. Excellent engine, but it was under powered even in its heyday. I had a GS430 and a 745 with 4.4, and the 745 had so much more power wasn't even a contest, despite the fact that on paper they had similar output.

And if you don't think your LS lost any power over the years, I have a bridge to sell you.

 

Agreed, but they'll swear that their 12 year old fading car with clunks and other issues is more reliable than someone with a newer car from a different brand. As we all know this is the human behavior of protecting one's tribe more than anything else. Logic and reasoning take a back seat.

 

Pretty much, yep. Also, sometimes when people have these "reliable" old cars, and something goes wrong (and it always does), they think of it as an exception that only happened to their car, and keep claiming their car is super reliable while dismissing other brands.

 

Feels no different than when I got it and the car still will haul azz when prodded. No complaints here. Every single time I drive the car I notice how lovely the V8 is.

BTW the BMW 4.4 had a 25hp advantage. That's significant, no wonder it felt faster. The 745i was faster than the LS430. In any case let's test compression on a 150k mile BMW V8 if it makes it that long versus the Lexus 4.3.

 

It felt like it had 100 more hp vs my GS430. There is no way in hell that car would make it to 150k miles, but I think 10 years 100k miles is just about maximum you can reasonably expect out of any car - beyond that point its a clunker no matter which make/model.

 

Disagree, but okay.

 

Where do you have this idea that an engine loses power as it ages?

 

Depends on the model and brand, maintenance as well My 4Runner does not feel old or worn at all. I would say it is about midway through its intended lifecycle. Husbands LX, yes definitely aged. Our cars are a little bit nosier at this point . New cars are wonderful to have, no doubt about it. New tech, absolutely But a lifetime of interest and mileage restrictions will never overcome having a car paid out right from the get go(just my opinion) and then benefits and contributions to my lifestyle. Earlier in my life, when cars were not as expensive, it was easier to get better value and trade them in sooner than later. Leasing definitely wasn’t as prevalent as it is now.

 

Its not an idea, it’s the truth. As engines age they lose power output.

As for cars aging, if cared for a good car can last well over 100k miles. Will it be worn? Of course.

 

Most of these things that cause loss of power are wear. Proper maintenance is what is required. The way you said it earlier, it sounds like there is no way to avoid loss of power, even with proper maintenance. Every engine will have a lifespan, permanent loss of power should not occur until the end of the lifespan, compression issues, cylinder issues, valves etc are very high mile issues. I think Toyota should has little wear occurred to a 4.7 at a million miles

I believe Car & Driver has demonstrated with their 30K test that some cars gained power/performance

Million mile Tundra:

“It was exciting to see the power figures from the engine in our cell,” said Gary Baker, quality team leader. “The engine performed better than many new engines off our line”

Even with proper maintenance you still have wear. Bottom line is an engine with 150,000 has absolutely lost power. Enough for you to notice? Probably not.

 

Lol then what's the problem? (rhetorical)

 

Also, when comparing reliability you can't compare a Lexus that has been meticulously cared for and maintained by an enthusiast to a BMW that was neglected by someone who didn't care. There are plenty of Lexus cars that aren't well maintained and by 100k become clunkers.

 

Totally agree with this
