is it still ok to use 5w-30 on my 183k miles d16z6? or perfer to use 10w-30?

dp

Between those two, I would use 10w-30.

Thicker oil is better for older/high miles engines. So, I would use 10-30

Westsideboy

Agreed...but you'll probably find that it won't "wind up" as fast with the thicker oil.

if u have a b18c with abot 40-50 thousand miles on it what weight oil would you people recomend also whats the best recommended brand oil to go with either synthetic or not?

eg_nezay

I would use Mobil1 10-30 fully synthetic

Nextelbuddy

and why would u recommend the 10 weight over the 05 weight? i am just curious thats all all my other motors were newr with about 10-20k on them so i always used 5w-30 but since this one has about 50k and is also a jdm motor i dont really know what to go with. since ill be running it a bit hard i want the best oil for it

I thought b18 motors should use 5w-30. This is what factory recommends.

hybrider

got my swap approx 1 1/2 years ago with 50k

and i have always used 10w-30 Mobil Syn

Mobile 1 is a good synthetic but it really doesn't make any difference if you use synthetic or not if it hasn't had synthetic in it from the very first oil change....on the other hand, synthetic is a good oil to use if you do a lot of stop and go drivin'.....

ejprimo

let me see, both 5w-30 and 10w-30 are 30 weight oils at operating temperature. even if you were to use a 10w-40 you wouldnt be able to notice the difference in horsepower.

me too.

I use 5-30 Mobil 1 synthetic because my motor is low milage, it doesnt leak or burn and I also read somewhere that it actuallytake less HP to move through an engine than 10/30. Of course were talking a small amout of power. And the main reason I use synthetic... because I'm a lazy piece of **** and hate doing oil changes.

ejprimo

if you are looking for more power, go use 0w-20.

B_CRUZ!

wtf?

5w-30 is recommended by Honda... why would you use any other weight? :shakes head:


if your motor leaks or burns oil, then fix it and use 5w-30. You are messing your motor up more by using anything else.

Caveman74

All companies recommend 5-30 because of better fuel economy

Ass_Clown

My mom has a b-series motor and we use Amzoil 5w-30. Only have to change your oil every 7500 miles.

at very low temps. the oil pumps at 5w..then as the motor warms viscosity moves up to 30..in temp zones where it rarely freeze s it best to use the 10-30w oil s..many race car s use a straight 30w since they re running at high temp s constantly

ejprimo

i was being sarcastic since some were concerned with horsepower numbers.

here's some interesting reading: http://theoildrop.server101.com/ubb/...=001653#000011

pdiggitydogg

5w for temps below 19degrees F and beyond
10w for temps above 19degrees F

so if you live somewhere where its cold right now...get the 5w...then when its warmer get the 10w

oldB18EF

isnt that supposed to be the other way around?

degooser

i was at my local honda parts dept and saw some 0-20...anyone know what uses this oil?? or what honda recommends to use this???

S2k maybe??
