Synthetic Oil

I am going to switch over to Synthetic Oil but what oil do you recommend using. I am thinking about Mobile 1 5W-30 or Castrol 5W-30. Which one is better or is there one better then those but not to much more in cost.

Re: Synthetic Oil

Royal Purple and Amsoil are the shit, but they are also what $8 a quart? Castrol GTX is like $12 per 5 quart jug and Mobil 1 is like $20 per 5 quart jug. Take your pick man, they are both good oils.

Re: Synthetic Oil

Mobile 1 or Royal Purple would be my pick, but why are you switching to synthetic anyway? Your car is used to regular oil, theres nothing wrong with it.

Re: Synthetic Oil

Is it that time of the month again for another oil thread?... Sigh...

We have covered this topic many times before and its all in personal preference and experiences.

I vote Amsoil to be one of the best I have ever used. But, if you are wanting a much cheaper costing oil then I say Mobil1.

doesn't let enough friction and heat build up. I know that doesn't make sense but these motors run hot.

Re: Synthetic Oil

Huh... you are right, that doesnt make sense. So it would be a bad idea to run royal purple? I was planning on that for the rebuild once I get 'er good and broken in.

Re: Synthetic Oil

i notice with my car, a little bit thicker oil is better. maybe it'll change when i get a new maf, but when the oil pressure seems to drop the car sputters a little bit. when i put quaker state Q advanced 5w 30 in, the car sputtered a lot. I jsut put in mobil1 10w 30, and it runs and idles easily 3x better since that oil change about 2 weeks ago. next oil change time im gonna try a 40 weight. when i changemy oil i also use STP oil treatment, and i can feel the difference with that too.

Re: Synthetic Oil

true story of me showing a friend amsoil

"hey man check out this amsoil stuff"

"holy shit, it smells like science!"

Although it's a dumb story, it proves a point. Amsoil doesn't even smell like natural oil, it is not a blend like most synthetics, there was a study done where it wasted every other oil out there.

Re: Synthetic Oil

yes thicker oil is better for our cars. I have found 15w50 to work best personally, but that was in texas heat where viscosity is a bit less
