does a blacktop sr20det take?

10w30? syenthitec?

 

oil type and weight really is based on personal opinion. some people run some oils for different reasons depending on how they drive, where they live, time of the year etc.

10w 30 would be fine and what ever you choose to run,make it synthetic.

here is some info you could take a look at

5w30 and 10w30 seem to be the most common. i run 10w30 mobil 1

 

also depends on the climate where your from

 

if your engine was rebuilt and has not been broken in i'd (so do most auto manufacturers) advise against synthetic oils. if your engine has an excessive amount of miles i'd advise against synthetic oils.

if neither apply i recommend mobile 1 otherwise use castrol gtx. oil weight as stated it really your choice based on your locatin and driving.

 

i used 20w30 but then again i lived in okinawa its hot year round
