Is there a problem with using synthetic oil instead (at say Jiffy lube or other non-Lexus garage) and extending the oil change period to 7,500 miles? Would that mess up the warranty?

That includes vehicles supplied with 3 year 90,000 warranty & those supplied with unlimited milage in the 3 year period. My last Lexus had a 9,000 miles interval, later models 10,000 / 20,000?

They are the only synthetic oil that goes that long. I been using it for many years in all my cars including both my Lexus'es.

Jeff There is no problem with using synthetic motor oil as long as it meets current API specification SM. Using motor oil that does not meet API SM or extending the oil change period to 7,500 miles would only mess up the warranty on your motor and emissions system, including the catalytic converter, not the rest of the car, and only if the non-specified oil caused a problem. -- Ray O (correct punctuation to reply) Back to top   Ads Advertising Sponsor Jeff@unknown.com Guest Posted: Tue Jun 10, 2008 6:33 pm    Post subject: Re: Using synthetic oil Yes, but my question is if doing so and lengthening the oil change interval would invalidate the Lexus warranty.

I don't know, but since if the vehicle is operated in the U.S., then one should follow the maintenance intervals for U.S. vehicles if one wishes to have the factory warrant the vehicle in the U.S. -- Ray O (correct punctuation to reply) Back to top   Ads Advertising Sponsor Ray O Guest Posted: Thu Jun 12, 2008 9:41 am    Post subject: Re: Using synthetic oil "Wayne" <pimentalw@nospamcomcast.net> wrote in message news:DMydnUqGyOtlt83VnZ2dnUVZ_vSdnZ2d@comcast.com...

It's a known fact. The eu has always had longer oil drains then us because they pay far more for their gas and oil.
