In Malaysia, German brand is always more popular compare to Lexus.. I think until today Lexus still cant beat BMW & Merc sales due to stiff pricing to start off and less aftermarket support. I were in dilemma in purchasing IS250 before, when i go and ask for spare parts availability and even half-cut area the thing shock me is that BMW got more spare parts availability to support compare to Lexus parts..

Lexus do not assemble else where other than Japan and north America.. Lexus in Msia are imported directly from Japan, and they are more expensive but the quality is top notch as they are assembled by Japanese. I have great respect for Japanese worker (I used to work in Japan many yrs ago). Japanese produce goods with customer in mind while others are with profit in mind, thus you see a lot of cut corners in other European brand

The popular models of Merc n BMW are CKD thus parts are abundance. Having said that, Lexus parts are built to last and the German parts are less reliable and need more "backup" instead.. heh..

Once tried the chemical spray, doesn't seem to do much. Twice did the traditional method where the shop opened the intake then manually scrape out the carbon with help of cleaners. Haven't tried walnut, maybe next time.

Parts are still easy to get for both new and half cut. Can join the IS250 and Mark X FB Clubs for lots of info.

Where did you do it and how much?

Thanks...
I am still thinking XE20 or XE30... XE20 for sure still number of them on the road, but I don't see many XE30..

Actually depends on the model you are comparing. If all german parts are less reliable why the latest Supra got the BMW engine & gearbox in it?

I did at Multiplex Auto, forgot how much but not cheap, maybe around rm300 now.

I'm more to XE20.. affordable.. XE30.. potong kepala..hahahhaa

Yup depending on models... Not quite sure does their plastic hose and sensors also source from BMW..
I am sure Toyota has scrutinize all the parts in their ZF gb and B58 engine..
However it is how BMW put them together which is different how Toyota does it..

Well the latest Supra is still too new to be proven reliable.

Your car is a low mileage car? you seem to do the "manual scraping" method quite often, every 30k km?

I dont think Toyota will risk their brand reputation for something un-reliable. FYI, BMW straight-6 is quite problem free compare to those 4-cylinder turbocharge engine. When you own both german & japanese rides in your family you will know each got their own advantage.

Already 150+k km now. I did every 40k km so far, maybe missed once to more than 50k also.

A lot of parts will be replaced by high-temp resistant plastic due to cost, weight & process time is less. Cars are not made to last over 10 years nowadays due to a lot of country are regulating emission standards of new cars more strictly yearly and car manufacturer need to come out updates or new models to meet these countries. You have to either live with it, or just stay-on with your old car.
FYI, even newer Toyota & Honda engine also got a lot of plastic hose nowadays. Just ask those road-side mechanic how many of them help change aftermarket metal hose after it is done.

Yeah at least should be reasonably reliable but I'm just saying better wait and see before using the new Supra as example of reliability.

Sure they have their own plus and minuses but based on most studies/surveys, Toyota and Lexus usually still tops the ranking for reliability and German cars not so much yet, even Mercs seem to have become less reliable maybe even worse than BMW. I don't dare buy German cars yet coz don't have enough money. Only can afford old Japanese cars, not even new ones too.

Seems older Toyota Lexus are better... heh

In term of reliability yes, but environment & safety will be on the downside.. Got pro & con also for both new & old rides.. Newer rides mostly need to meet certain safety & emission standard so you still got some advantage for newer cars.. Just think that the money save from fuel can be compensate into spare parts..

Well.... the older Lexus might be thirsty and need some refurbishment, but the 2nd price is low to start with so that kinna offset it..
Safety wise i think basic active and passive system are there, just lack of those advance radar sensing stuff...Lesser electronics, less things to go wrong

Some ppl have the passion of fixing and refurbishing older cars, while most just want hassle free and pay the price for a new car

Hi bro. Do you feel any difference after getting rid of those carbon deposits?

Also what opinion do you have on Caltex techron concentrate plus?

Not much difference to be honest, just slightly better response.

Never tried Techron but it supposedly good coz it contains the PEA active ingredient which is the only cleaner that can work in the hot environment inside engines. I instead use Gumout Fuel System Cleaner which also contains the same, buy at ACE at rm16+. Other choices that contain that ingredient are 3M and STP Fuel System Cleaners (not fuel injector cleaners ya).
