Can I change my car's oil to another brand after using only one for three years?

It's Toyota Corolla 2002.Can I change my car's oil to another brand after using only one for three years?
Changing brands is not an issue... changing viscosity, or types can be an issue. 10w40, SAE 40 are two different viscosities and one is a detergent additive. Changing can lead to gasket failure. Keep with manufacturers recomended type but brand, Synthetic/ synthetic mix will not factor into this.


One disclaimer though, try to go with a name brand, this ensures some sort of quality control. No name, dollar store brands tend to have wide fluctuations in their consistency.Can I change my car's oil to another brand after using only one for three years?
The brand of oil does NOT make any difference, they all have to meet certain specifications. All that matters is that you use the right grade recommended in your owners manuel.
yes, oil is oil. There really isn't any difference from one brand to the other.
Yes you can. But it depends if the car manufacture recomends.
The ';you can't switch back after you go synthetic'; is a load of crock....





Yes, perfectly fine to switch.....








(btw, napas oil is made by valvoline, a oil found to be THE lowest oil in the additive department, just enough to pass the api tests)
No problem, change the filter too
Yes you can. I use napa
If you are planning to keep your car and want to take the best care of its engine, I recommend ( and use nothing but ) AMSOIL synthetic motor oil, transmission fluid and, even gear lube in the differential. Its slightly more expensive than, say Mobil 1 or Castrol but, definitely worth every penny. Once you try it, you'll agree too. Just a few of the benefits of AMSOIL .... Lower operating temperature ( mine went down 10 - 15 degrees ), Less engine noise ( valves and lifters ), Increased MPG ( I added an average of 2 MPG ) and, $$$ savings ( both from the increased MPG and ';extended drain interval'; with AMSOIL ).





Check this site out for more information and online ordering if youre ready to try it for yourself. EVERYONE has their own opinion of which oil is best but, everyone who has tried AMSOIL ( that I know of ) has stayed with AMSOIL.

In general, if you use a conventional motor oil you can use any other brand of conventional motor oil of the same viscosity ( like 5W30 or 10W30 for your application ) however, once you switch to a synthetic motor oil ( again, of the same viscosity ) you MUST NOT switch to a conventional motor oil again ( you can though switch brands of synthetic oil, if you want to ).





As for switching from Synthetic back to conventional motor oil, try it if you like ( as 572ci says is ok ) but, its your engine.
Yes. Any quality oil will be just fine. I would recommend full synthetic if you plan on keeping your vehicle for a long time.
Yes you can. Valvoline is good. Or Quaker State is good too.The brand doesn't really matter. Just try and use the same weight.
yes, and the best brand to use is quaker state
YES,YOU CAN.AS LONG AS U CONTINUE TO USE THE
