do you have an oil pressure gauge? what does it read idling on a 90* day?Originally Posted by BoostJunki3

no its not lol 5w30 is like water compared to 10w30weights can be misleading. for example mobil 1 5w30 is thicker then mobil 1 10w30

im not gonna waste my time on an argument when there is rock solid proof on their website. look up and interpret the cSt's of both oils and you will then understand
06-25-2010
really? 5w-50?
06-25-2010
dunno who your buying oil from cuz they are wrong. Just for ****s and giggles i googled some proof for you. Read the first couple short descriptions on the page.... 5w30 is thinner, hence, why you run it in winter because it flows better.im not gonna waste my time on an argument when there is rock solid proof on their website
5w30 thicker than 10w30 - Google Search

5w30 offerers lower thickness for winter when its colder out thats what the 5w stand for winter weight

hmmm you must have missed the second half of my post

planning on changing mine soon and am planning on either mobil1 5w30 royal purple 5w30 or amsoil 5w30
06-25-2010
mobil 1 5w30 and a purolator pure one. BTW, oil volume is more important than pressure. Think about it for a second: when lubricating a drill bit for instance, do you want high pressure spray or high volume?
06-25-2010
yes 5w50.. run i.. you will love it, it basically stays as a 5w weight/ viscosity without thining out at even the harshest driving. therefor staying at a constant 50psi oil pressure even with the car completely heatsoaked 5 w30 5w40 and 5w50 will all be the same thickness at 0*

How do you think you are going to get the volume to move around the engine? Pressure

well nobody got the zzp oil volume kit? i got it put in but i dont have a op gauge, and i ran 5w30 syn whatever brand is on sale, and i use lucas syn oil stuff to.

Hate newb up the thread but maybe some of you can educate me on this topic. If I live in Seattle and the weather is neither crazy hot or crazy cold what is the best option for me? I am religious about my oil changes and always use Castrol GTX sometimes 20w50, sometimes 10w30 and every so often I treat it with Lucas Oil.
Am I just wasting money with Lucas Oil?
Should I stick to the same weight, and does changing it effect performance?
I drive alot, average about 300-400 miles a week so I do alot of oil changes, if I should change it up let me know thanks.

I would not run 20w50 it is to heavy..the only way I would run 20w50 would be at the track on a very hot day.. or in an engine that is worn out 5w30 or 10w30 is your best bet 5w30 winter 10w30 summer lucus ok..but I would rather put my money on a good synthetic instead !!
10-05-2011
Ok good to know, so should I just switch to Castrol Sythetic or pony up for the RP? I dont mind the added cost I just want to know if its actual making a difference?

For the amount of miles you are driving, I would go with Amsoil Synthetic. It lasts up to 25,000 miles and is a very high quality synthetic.
AMSOIL - Signature Series 100% Synthetic 10W-30 Motor Oil (ATM)

Thanks for the suggestion, despite it being rated up to 25k how often would you change this oil? Stay on the 3k schedule?

0W-20 season is upon us... well at least its getting there...
