i was joking around cuz all these name brand oils are being said so i thought i would say something! but i use mobile 1

 

switching to synthetic doesn't "clean the old sludge and **** out" as you may think. switching half way through a motors life will promote leaks in the seals because the "synthetic" additives that they use to again "clean the old sludge and **** out" causes the seals to deteriorate and therefore cause leaks. and about the bold statement, where is your evidence to back that up since you're so educated in this manor. i for one have seen this happen many times, and it has been tested as well. it will not harm you're engine as much as you think, but it is recommended to stick with conventional oils when you've been using them. a half/half mix is fine as well.

 

well i didnt do the half and half mix, i jus ran 4quarts of royal purple after using nonsyn oil, wut should i do for my next oil change ?

 

oil is oil, just use whatever you want, that's why they have so many choices and brands for you to choose from, just pick the correct weight (depending on time of year)

 

whats the correct weight for this time of year, how bout for winter?

 

that's just a matter of opinion, you can run 10w30 or 5w30, both get the job done all year long. the weight determines the viscosity and the temperature it needs to reach before it's optimal performance. do you get very cold winters?

 

dont know what would be concidered very cold lol, but i live in nyc so it isnt extremely bad, but yes it gets cold

 

if it's very cold, you can run some 10w40, if it's normal, you can just run normal 10w30. the colder the weather is, the thicker the oil is, so you would want a thinner oil to compensate. but in the end, it's just a matter of preference.

 

k thats good to know, thanks for the short lesson on oil
