I doubt you will ever have a problem going to a higher weight oil; e.g, from 5W30 to 10W30, 10W40 or even 15W40. Oil pressure is not affected since that is determined by a regulator in the oil pump. Cold flow might be a factor when it gets really cold. In old cars I've owned, I used to change the oil once a year. Never had an oil related failure; just really dirty oil. All the hype about synthetics and such is moslty just that too.......Hype. Heavier weight will lower mpg a small amount...maybe...depends on driving style; but will not blow seals and destroy the engine.</p></blockquote><p></p>
