No. My Subaru Impreza calls for 0w20 synthetic. In the quest for EPA numbers, mind you. In the summer oil burn off can catch you off guard and the oil light pops on between oil changes. I use a mixture of 10w30 and the recommended oil and dont have the problem anymore. Winter I mix with 5w30. If your Suzuki has alot of miles on it you are probably better off with the heavier oil anyway.
