Got my first one at 200 miles, second at 1500, third will be at 5K, then depending how I drive - probably every 5K, then after 10K I'll go synthetic.
haha - nice. Got me laughing good.Originally posted by TCrazy@Nov 3 2004, 08:06 PM
dont try to be a detective and get off my case
i can agree with you on that 5k is more that adaquate. 3 is what everybody is used to. the tC is a great car. but, it is still a car.Originally posted by TCrazy@Nov 3 2004, 07:43 PM
Got mine at 3000 miles. We've been through this before and it causes nothing but flames......however I will state that the Scion engineers say 3000 miles is perfectly safe (read the manual, its actually like 5k miles)......and until anyone here comes up with solid proof against there reasoning..............early oil changes are pointless. -t
Would have to agree for the most part. I'll switch to synthetic after 6K and before 10K. Common postings indicate waiting for it to wear in before getting into syn oil. Wished they would break it in for us and ship it to use like the German cars. But then again, we paid much less!Originally posted by Geneo@Nov 4 2004, 11:54 AM
Change it whenever you wish as long as it is at least every 5,000 miles. Years ago Toyota had a oil change recommended at 1,000 miles and was covered under a 1,000 mile check-up. Belts were tightened and the like were done. I think that if it gives you peace of mind to change it real early...go do it. Hey, it does not hurt to change it to get out any unwanted material floating about in a new engine. The real issue is with the owners who do not change the oil as often as recommended. Toyota's oil gelling issues were caused more by that problem than anything else. Petroleum baseed oils will absorb moisture and can contribute to gelling issues under high mileage changes. Synthetic oils will pretty much stop this problem, but I personally would wait until about 10,000 miles before making the switch to synthetic... to allow proper break-in. I see many of the posts say this as well.
So change the oil...it sure is not going to hurt anything.
I said that I would not switch to synthetic oil until 10,000 miles to allow for proper breakin and seating of rings etc. in the new engine. My 10,000 mile figure is just when I plan to switch over to synthetic. That would make it my second oil change. I would switch to synthetic due to the superior lubrication properties and the fact it flows much better and faster in a cold climate. While Richmond, Virginia..where I live ..is not super cold in the winter, oil does thicken up quite a bit in the winter and does not flow well when first started. You can hear the difference in engine cranking speed on those real cold mornings. It is not imagined...it does really turn over about 14% faster.Since everything you can read on engine lubrication states that most engine wear occurs when cold starting it makes sense to get that oil flowing as fast as possible. Petroleum based oil is just no competition for synthetics. Synthetics flow easier and faster, absorb and retain less moisture and for the most part are better on lubricating modern seals and gaskets in engines . This will lead to less oil leakage problems down the road. Notice I said leakage in MODERN engines. Using synthetics in some older engines with old gasket materials can cause more leakage. I am the voice of experience on the old engine leakage. My Fiat Spider does not like synthetic and will leak oil badly with synthetic. Of, course it is a 25 year old engine that has never been rebuilt and of course it leaks on my garage floor....after all..it is a Fiat. It is Italian tradition....Originally posted by nguytu@Nov 4 2004, 04:42 PM
Per your comment on the switch to synthetic after certain mileage level, I'd like to understand (as a newbie to oil change and such car maintenance activities) the reasoning for switching to synthetic oil from standard oil.
