So, she should be using higher weight engine oil like 5-40 or even higher right? and its a must to be fully synthetic? Since its a 10 year old car. <br />And can I just switch engine oils or need to flush? She&#39;s using Shell semi synthetic. <br />Or rather she needs to fix the root problem of engine oil leak? but I don&#39;t think she wants to do that <!--emo&:stars:--><img src='http://static.lowyat.net/style_emoticons/default/rclxub.gif' border='0' style='vertical-align:middle' alt='rclxub.gif' /><!--endemo--> <br /><br />Thanks guys. <!--emo&:)--><img src='http://static.lowyat.net/style_emoticons/default/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif' /><!--endemo--> TypeRZ The Fast &amp; The Furious Sun, 29 Jul 2012 13:29:28 +0800 http://forum.lowyat.net/topic/2295072 Hi sifu&#39;s. <!--emo&:)--><img src='http://static.lowyat.net/style_emoticons/default/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif' /><!--endemo--> <br />Wanna ask that does foaming the door sills give the same effect as installing the side bars 3 points? <!--emo&:hmm:--><img src='http://static.lowyat.net/style_emoticons/default/hmm.gif' border='0' style='vertical-align:middle' alt='hmm.gif' /><!--endemo--> <br /><br /> TypeRZ The Fast &amp; The Furious Thu, 05 Apr 2012 19:32:52 +0800
