Switching to synthetic oil problem
My yaris has 8,500 miles. I change oil every 3,000 miles. the first 2 oil changes I used conventional oil. I'd like to switch to synthetic oil.
I called a repair shop and they told me I can't switch to synthetic oil. This will damage the engine because I already had 2 oil changes with conventional oil. Is this right? Thanks. |

It's bullshit. Especially on such a low-mileage engine, it's always safe to switch _to_ synthetic oil.

I remember a bunch of old-timers saying that you shouldn't switch to synthetic right away... it's best to wait 10k-15k miles. Do some searching and you should find some of these threads.

It's OK to switch to synthetic at anytime. In your case, go for it.

there's a mountain of info lurking in these waters, you just gotta stick your head in to see it.
ill throw a few things out there that aren't my opinion (my opinion, go at least 3k on factory oil then do what you like): -factory oil is break in oil and needs to be run 5k -factory breaks in motor before they ship it, you can do whatever you want as soon as you get it -you should change your oil as soon as you get it home, then again at 500 miles, then again at 3k. (just because its 1500cc doesn't mean its a motorcycle motor...) |

I switched at 20k, best thing I ever did for my car. You can switch at anytime. The only reason old timers didn't like it is synthetic is not compatible with leather engine seals-which have not been used since the 1950's I think I heard. Synthetic flows better than conventional-so if you had an engine with a minor leak, synthetic would make it leak faster-that's the only down side I've heard about synthetic. Even the prices of shelf brand synthetics have come down with sales making them closer in price to conventional.

Thanks for all the replies. I think I will switch to syn oil. While most people use Mobil-1 or Amsoil syn oils.
How do you think about the SuperTech syn oil sold at Wallmart. Very good price. Is it a good? |

i waited until 10k, but that's only because i was given a 'free' oil change coupon from the dealership when i bought the car and after that i had roughly that many(i use 'free' because the way i look at it i paid 12k for an oil change :lol: ).

Id wait till about 10k to switch over. That way your engine has time to fully break in using conventional oil. Using synthetic right off the bat may make your engine take a little longer to break in. If you must use synthetic before they royal purple makes a break in oil. Never tried it though.

* Engines are not broken in at the factory. Engines are first run only after final car assemby when all engine support parts are installed. Having said that .... With modern machine tools, critical engine parts are now made more precise and the break in procedures of old are no loger nessary for the most part. Just take it easy for the first 2k or so. However, personally, I like to change oil initially at about 2k miles as during this period, you have the most (nessary) break in wear and there are microscopic metalic particles suspended in the oil that should be removed. Finally, synthetic is not some mysterious miracle oil that needs special conditions etc and can be used at most any time after break in. It can also be mixed with "dyno" oil in any proportions. |

i switched on my jeep at 175k miles. i had a valve cover gasket leak but that's only cuz dirt was actually clogging the leak and the synthetic cleaned it out. it was time to change that coark gasket to rubber any way.

I'm sure its decent but I would stick to proven syns like mobil 1 amsoil penzoil plat ect. If you are running syn you can run longer oci, might as well have the good stuff in there |

If you use AmsOil, the engine will last 300,000 miles. If you use SuperTech, your engine will last 299,999.98 miles....save your money and go for price because spending bigger $$ on boutique oils is often a huge waste of money and their "extra" protection is so small you'd need an ant's a-hole to see the difference |
