same exact driving conditions, driving to and from work about 20 miles each way, 15 of that highway driving. and a lot of city driving on the weekends. redline it probably every few days.

castrol syntec is the report of the left and mobil is the report on the right

the syntec was run for 5200 miles and the mobil 1 only 3750.

i don't think i'll ever be using m1 again.

 

I switched from Mobil 1 to Castrol about a 6 months ago. I will never look back.

 

Castrol Syntec is all I use in the G and the wifes Maxima! Thanks for sharing your results.

 

castrol syntec for me as well.

 

Nice work!

 

for those of us who dont know what the hell all those figures mean ..

explain why castrol syntec is better than mobil 1 ..

 

all the metal wear levels are lower or equal for the syntec versus the mobil1... and the syntec was run 1500 miles MORE than the mobil1. also, most of the anti-wear additives are higher than the mobil 1

so essentially, the syntec out performed the mobil1 in almost every category even after being run 1500 miles longer.

for more info on what each element is you can read this site: http://www.blackstone-labs.com/gasol...port_expl.html

 

i'm really happy the iron wear went way down when compared to the m1. i was not excited to see the high iron wear with m1 after 3750 miles

 

which castrol bottle is this one??? i always wanted to try it but i dunno which one to choose...isnt the castrol cheaper than the M1???

 

man this is so confusing lol. Now this stuffs better then M1? I cant seem to choose a certain oil because one seems or might be better then the other.

 

I used Mobil 1 for 125K miles on my last Z, it's still on the street running great and I never had to make any serious repairs except normal maintance. That alone should tell you that Mobil 1 is damn good synthetic oil! Screw the tests this is real life experience....Plus, when my rear main seal failed they pulled my oil pan it was as new inside with no residue/gunk at 117K miles. This is only possible with quality synthetic oil....

Oil is Oil. It is one of the most tested substances on earth. How many cars do you see running past 200k miles when someone changes the oil on a regular schedule?! The point is, if you change your oil on a regular basis it doesnt matter what you use.

Edit: Ohh and i use Mobil 1 but castrol is good too, as long as it lubes!

 

i started using castrol syntec last year and i put 0w-30 in.. i dont remember my research last year, but i concluded that would be the best to put in my car..

autozone is selling like 5qts of syntec and a filter for like not even $25, but the ad showed 5w-30. i dont remember if i read about the 5w-30 last year and there was a reason i chose the 0w instead...

should i put 0w in again?

 

My first Service was Mobile, but Ive asked them to switch to castrol after that, pay an extra $20 for it.. money well spent..
