G'day All. Just New To The Site. Need Some Info On E-tecs. There Could Be Some Info Elsewhere In The Forum, But I Saw Too Many Pages!! Want A Motor About 90 Hp For A 550 Formosa I've Ordered. Struggling With All The Hype Of No Service For 3 Yrs. Does Anyone Know How Much It Is And How Often After That? Also, Are They Heavy On Oil? Was Told You Must Run Synthetic. Supposed To Be Expensive. Good On Fuel, But You Lose It In Extra Oil? Help!!!!!!
