Question type: General

Is it OK to use synthetic oil in the toyota vehicles and will it affect any oil seals? If it does then do you reccomend using a bottle of sealer with the oil change?

That depends on the year of the vehicle. If it has been running on conventional oil for 10 years then its best to stick with conventional oil, (although I have never had a problem) I have heard of people that did this and they experienced leaks. I personally would not use a sealer (I have seen them cause problems in the oil pump or eventually wear and the leak came back) and replace the gaskets. If you are not into replacing gaskets on an older car then stick to conventional.

Hi;Thank you.As I understand it the rear seal has been changed from the old type and prevents most leaks.It's confusing cause they also make a mix of synthetic and regular oil.Perhaps that would be better to use,though I find that the toyota runs cooler than a vehicle with a cast iron block. What do you think? Don

It would mostly likely be better to stick to either conventional or synthetic as not all places carry the mixture. It will be easier to remember when buying too. The Toyota does run cooler thanks to the aluminum engine. FYI: Although it does run cooler it is more susceptible to heat damage when it over heats than a cast iron engine.
