I never said there was a difference. The type of filter on the car is a good indicator of what type of oil is in the engine. Someone who sues synthetic is more likely to use a more expensive filter, rather than a $2.00 Pep Boys filter.spray004 said:If you have that many miles on your car, I would not switch to synthetic. Most people don't use synthetic (unless the car came factory with it). Do not listen to what dude said about looking at the damn filter, he's doesnt know what he's talking about. There is absolutely no difference in oil filters for synthetic or conventional oil.

The only thing I see wrong with this statement, is where I said "definitely." You may use good oil and a cheap filter, but if I pay $25 for oil, then I'm not going to slap on a shit filter and need to change it in another 3,000 miles. Not everbody knows that there is a difference between filters. Besides, it does not even matter what type of oil is already in the car. If the previous owner had been using the same type of oil for 113,000 miles, will keeping the oil for another 2 or 3k hurt the engine?flyingtoaster said:Get under the car and look at the filter. If its a Honda, Frahm, or Purolator, then he may be using regular oil. If its a Mobil 1 filter, then the oil is definitely synthetic.
Yeah, that's true. Any new oil is going to be better than any oil that's been in there for 30k miles.AccOrDZteCh said:if i buy a car, usually i take it down and inspect and change the sparks and stuff...and i just might as well change the oil ...you never know what he had or when he exactly changed it...
