tomtbone Posted July 2, 2007 Report Share Posted July 2, 2007 to each his own opinion - and repair bill simply not true....you need to get educated. go over to bitog forum and do some reading. You will have no problem going 7500 with a decent synthetic like syntec 0w30, PP 5w30, or probably even M1 Link to comment Share on other sites More sharing options...

Che'_Moderator Posted July 2, 2007 Report Share Posted July 2, 2007 do not take my word for it, please refer to the Oil Analysis charts archived at BITOG.

SkyWriter Posted July 2, 2007 Report Share Posted July 2, 2007 There is good info there but a lot of really bad info there also.which always leads me to here:I've found the more people with opinions the less you actually get out of it.and so, i'll stick to my regimen. ;) Link to comment Share on other sites More sharing options...
RedTurbo850 Posted July 6, 2007 Report Share Posted July 6, 2007 several reasons, 1-i'm paranoid and i have a hard time being convinced to go over 4k btw changes, 2-I have several cases of dino oil which i got at .99 a qt by pulling off a double cupon and rebate on a newb at schucks.I just wanted to make sure i didn't HAVE to use synthetic, wasn't trying to revive the dead horseThat's funny because I got 6 qts of Vavoline Syn for $.99 (after rebate).Sorry for the hijack lol.

RedTurbo850 Posted July 6, 2007 Report Share Posted July 6, 2007 Where?It was a promotion I believe a month ago at Checkers/Kragans. However...The oil was only 3.49 a qt... Link to comment Share on other sites More sharing options...
pro_star Posted July 7, 2007 Report Share Posted July 7, 2007 about the going from dino to synthetic getting leaks thing....I heard that the reason that happens was because the leaks were there to begin with, but dino is a little thicker so it won't run through the leaks as readily as the synthetic will?if I'm wrong, have mercy on me. if i'm right...dang i get a gold star ;) Link to comment Share on other sites More sharing options...

It only exposes them. Link to comment Share on other sites More sharing options...
PyROTech Posted July 7, 2007 Report Share Posted July 7, 2007 i use what the manf recommends, mobil 1 and change based on my driving conditions, but supposedly the car will do 15k on it with normal non agressive use (according to the maintenance schedule and computer count down to service). But with hard driving my car tells me to add oil as its burnt and adjusts the service remaining based on the oil level and supposedly on some way it measure the quality of it (i dont actually know this but manual says this i believe). After i add oil and how much i add it will extended the service count down. As a rule of thumb i do oil and filter very regularly regardless of what the computer tells me and dealer says im just wasting my money. But for some stupid reason they bug me about my fucking cabin filter more than oil which i could really careless about.And the bloody dealer has this stupid "a" service which is basically a once over of the car and costs a fortune, most of the stuff you could do yourself (ie. check horn, headlights, brake lights, blah blah blah) something that should take total of max 30min for a moron all to check really well, but has some excessive labour cost that i dont get. But i like to have a perfect no questions asked always benz dealer service done so selling the car gives the buyer confidence the service wasnt done at bob's drunken brothers auto mechanic shop.

It's a giant rip off because at the end, they don't fix anything.... Link to comment Share on other sites More sharing options...

It's not that the synthetic is creating the leak, it's just that the plain ole dino was too thick to meander its way out. Link to comment Share on other sites More sharing options...
