10w30 or 5w30??

[ekrican77]

its always been bugging me... which 1 is better to use??? i dnt understand and havent taken tha time or money to expirment wit it... do they relle make a difference or??

i always used 10w40 its a lil thicker n better in my opinion

[JdmCoupe91]

They def. make a difference...
10w30 is wayy thicker than 5w30.

Personally, I use 10w30 for high mileage and its does just fine...
But if its pre-100k, or a crate motor (( ordered )) I'd go full synthetic 5w30 (( mobil 1 or something ))

The motor will run sluggish if it takes 10w30 in its early miles.
Someone can correct me if I'm mistaken.

Hope this helped.

x2 ^^^ full synthetic isnt good for these old motors in my opinion, ful synthetic should only be used in the up to date newer cars, stay conventional, save yourself the headache. BUMP

[83rolla]

^5w30 is thinner than 10w30 ._.
And 5w30 is good for all year around...

I just highly recommend you DON'T use it on high mileage.

[lsvtecrex]

yeah i meant 5w-30 cuz its thinner and better for your engine
