IMO I dont think its a waste of money, unless youre changing it every 1k or something, but at 3k its good cause oil breaks down and since you like me have the 350, our cars would benefit. The car really feels like junk after 4k IMO.

 

I thought I was the only one experiencing that. My car was only at 4200 or some add and felt kinda sluggish. Took it in for 5k service and runs like new again.

 

[sarchasm] Sounds like the increased viscosity of your oil from all the metal shavings in there are slowing things down... The increased resistance within the sludgy oil must be slowing down the moving parts of your engine and you are losing horsepower... Must be a loss of 30-50 horsepower if you can feel it.. Good thing you changed your oil at 5000 miles, if you had gone to 10,000 miles before an oil change you probably would have lost over 100 horsepower... [/sarchasm]

 

I have 18,000+ miles on my car...i did my first oil change at 1500 miles with synthetic oil and i have changed it every 3,000 miles since using synthetic. Oil is Oil. It burns and breaks down...I don't believe that it is a waste of money...

 

This is not true, every oil manufacture has a different formula (different base stocks) and additive package. This is why some oils last longer then others.

anyone try olive oil?

 

I'm not saying there aren't differences between oils, I'm just saying all oils are the same

But honestly, do you really think there is more than a trivial difference in longevity? And even if there is, what is the difference? The motorsport oil (or whatever it was) in my Jaguar lasted 3 years... So who cares if another oil lasts 6 months more, or 6 months less? I mean, we all change our oil at least every year, right? So, if a cheap oil only lasts 1 years, and a quality oil like motorsport lasts 4 years, it's sorta pointless anyway... Almost like 100 octane gas in an IS350...

 

im using chevon 5-30 should i change at 3k or 5k? how many quarts do u guys use. i needed 7

 

You bet



....and take it from me, as often as you guys say you do it, and decent oil will do.

 

LMAO!!!!! AH HA HA HA HA HA!

 

Do you get an older design of Lexus engine over there? The European Lexus engines go 10,000 miles minimum between oil changes.

 

They think Americans are less intelligent and will pay for oil changes every 5k miles...

Apparently they are right

 

Well the automakers excuse has always been the climate is harsher in North America... Total BS. I say our ignorance should stop now.

 

6.7 quarts is the correct amount of engine oil fill.

don't put in all 7 quarts.

you're engine might start acting funny . . .

chevron's a good oil, by the way

Edit - Toyota/Lexus now recommends using 5w-20 in our engines.

If you drive normally then 5k should be fine.
