Hello pals how r u guys doing?I hav a 2005 Corolla,d car has really been serving me well.One thing is i always change d oil every month end wen i receive my salary.This has been my normal practice.My question is,is it advisable to continue lik dat?Wat do u guys tink?

when making a post on cartalk that requires feed back try and include the make of vehicle, trim, engine type,(I4,v6,v8.........) and other relevant information that will enable others give solutions more accurately.

Toyota Corolla doesnt hav anytin lik V6 or there about.Talking about Toyota Corolla,d only info u need to know is d model,which i mentioned earlier as 2005.

Sorry about the mix up.Very conversent with toyotas, unfortunately did not see the car make or trim when you first posted, could have been my mistake. Reply remains the same.

Yeah, don't change by the month, change by the distance driven.. If you are not driving 3k-5k miles in three months, then you can change your oil every three months...

The money spent on new brake calipers, saved me the money i burned in gas to power through the tight grip of the bad brake calipers... So will synthetic oil smother engine function save petrol use and money spent...
