maybe i should have asked before i bought it, but does anyone have any experience with the mobile 1 filter? It is bigger than the fram filter that's on the car now. I think it's supposed to hold more oil than stock.

also, is 10w30 (fyi, it's castrol gtx) ok for summer? it's humid and about 70-90 degrees farenheit here. I bought a case to do an oil change this weekend, should I return it and buy a heavier weight, like 20w50 or will the 10w30 be fine?

 

Mobil one filters are quite good, much better then the fram crap thats on there. 10-30 should be fine too.

 

wow, that was quick, thanks

 

yeah.. fram is garbage

 

10W30 is fine for starting in temps under 85F... if you are starting and running above 85F you are probably better off using a 20W50 or a 15W40

 

If it's that hot you should use 20W50 to be safe.

Some lucas oil stabilizer wouldn't hurt either.

 

isnt that lucas stuff uber thick? Anyone try it? sorry don't mean to thread jack...

 

Yeah it makes the oil quite a bit thicker. I use it every other oil change.

Sometimes I just put in 15W40 when I use it.

 

something wrong with the quality of your oil, that you need to use snake oil every other oil change?

 

Yeah for reals why would you use any additives dont you know there all a bunch of bull well except for some fuel additives those can actually do something

 

There's nothing wrong with the quality of my oil & gear oil I just add a climbing additive. Is there a problem with that? Say what you want.

Cheers!

 

In fact im really sorry and take back what I have said. Icemark is right.

Im actually draining my ******* oil as we speak! (seriously) lol

Sorry for telling you to add it. Reading this test on the stabilizer scared me.

I will never go by what I hear anymore! Just by the facts.

 

what will happen if I use 10w30 when it's above 85?

 

depending on the oil brand, the shear film may be too thin to protect the engine from wear, because the oil is too runny

 

so i should probably get some 20w50?

 

yes

 

or 10w50
or 20w40

i don't know the difference

 

Go Royal Purple!

Put in 20W50 but 15W40 is good enough

 

I ran mobil 1 filter with castrol gtx 10w-30 for 2 summers in the FD with no problems. It does get thin and you'll notice it upon startups after short shutdowns. You'll see it on your oil pressure gauge if you have one.

Im running a mobil 1 filter with RP 10w-30 in my DD now with no problems as well.

If you track your car or do alot of driving in the summer with long trips, go 20w-50 to be safe. If you're driving short trips a couple of times during the day, 10w-30 should be fine.

 

i got some castrol gtx 20w50.
i'll change my oil this weekend if it doesn't rain
