silentqreaper Posted June 29 Report Share Posted June 29 Hey what do you guys thinks is the best synthetic? And do you know if it increases hp and gas mileage? Quote Link to comment Share on other sites More sharing options...
2kool4school Posted June 29 Report Share Posted June 29 You will notice very little or almost no increase in HP and gas mileage. The only thing I can say is that it provides far better protection and will allow you to drive more miles before changing it. I use Mobil 1 or Castrol Syntec in both of my vehicles.

ou812 Posted June 30 Report Share Posted June 30 I have a Grand Cherokee, so I don't really care about putting synthetic in it.In the bike I use Repsol Moto 4T Racing 10W-50 full synthetic. I don't want a conventional oil in there when I am bouncing off 11-13K RPMs. Quote Link to comment Share on other sites More sharing options...
asonofabeachnj Posted July 1 Report Share Posted July 1 Id look into the Castrol Sytec-blend, its a tri-blend of motor oils. Full synthetic could be dangerous if you decide to switch back to regular motor oil, cause leaks etc... 3rdflapartamnt 1 Quote Link to comment Share on other sites More sharing options...
Guest onisakura Posted July 1 Report Share Posted July 1 Yeah, its not a good idea to switch back after using full synthetic. Mobil One (15W50)is what i used to always use in the S2000 but that was when i was racing and beating the crap outta it. It got a little expensive after a while though, I was putting about 1200 miles on it a month. I put castrol syntec in the civic. Quote Link to comment Share on other sites More sharing options...

guidew Posted August 3 Report Share Posted August 3 HAHAh this debate has been on going for years especially when switching back and forth. We have found that when you switch with true syn oil like Royal Purple that over time it could create a problem. Remember true syth is very thin (lubircates every damn thing) which can then seep through gaskets. Down side is we are unsure if it was teh gasket itself from wear and tear or if it was becuase of this.Now which to use, look at the owners manuel. It like putting premium gas in a motor thats made for regular. Motors now a days are made to work 100% of the time all the time and now with the new ratings scale for Hp output it might get worse. Most motors are made to run on dino oil. 3,000 miles and oil change. Unless you have a heavy modded motor (fuly n/a or boost) would i go and put syth or tri syth. Or if you have a truck and haul a lot of weight around same deal.If you want to go syth, go tri syth, since its a blend of from 2-4 oils and will do better then a fully syn oil which you probably wont use to its fullest.hope that helps Quote Link to comment Share on other sites More sharing options...

You cannot because..............Down side is we are unsure if it was teh gasket itself from wear and tear or if it was becuase of this.This is what is actually happening.If what you claim to be is true "true syth is very thin (lubircates every damn thing) which can then seep through gaskets."................then simply using synthetic oil would cause gaskets to leak, why would swtiching back to convential have anything to do with it. According to this logic, just using synthetic oil would make a gasket leak, which as I said befor is a myth. Quote Link to comment Share on other sites More sharing options...

I will say that switching every 3k didnt make a damn diffrence. But i will stanbd on unless you own a high RPM car or a car thats heavy n/a or FI its not worth it. Car manufactures test there engines using dyno oil not a fully syth oil or tri syth. If you want to throw away money with a stock car just use tri syth.

guidew Posted August 9 Report Share Posted August 9 I used syn in my CBR 600 cc also, but its not needed in a car that has a 6,500 redline thats for sure. You cant compare a spot bike redline to that of a daily, fuel efficiant car. Lets compare apples to apples...not an apple to an orange Quote Link to comment Share on other sites More sharing options...

Lets compare apples to apples...not an apple to an orangePorsches and Vettes come from the factory will Mobil-1 full synthetic in their engines, and more and more high end manufacturers' cars are recommending full synthetic for their cars. I HIGHLY doubt they would do this if they thought it would result in higher maintenance costs down the road from leaking gaskets and such, or if they didn't need/benefit from it. Let's just put it to bed...................it's a myth. Quote Link to comment Share on other sites More sharing options...
guidew Posted August 9 Report Share Posted August 9 Porshes and vettes..again your just adding to what i said. These are high end sports cars. Again they do not use full syth, they say they do but its a blend or a tri syth. When they start to use royal purple then let me know. And it was never stated if they did use full sythetic all it said was Mobil 1 factory fill and this was the same for Camaro, Firebird, Corvette, GTO. My dad has 2 vettes and no where does it state full syn just Mobil 1. Quote Link to comment Share on other sites More sharing options...
ou812 Posted August 9 Report Share Posted August 9 Whatever you say.According to Mobil's site it is a full synthetic. I think you should sue them for false advertising since according to you they are lying:http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_FAQs.aspx#FAQs3 Quote Link to comment Share on other sites More sharing options...

Or friction modifiers.Also note they say its sythetic correct it has PAO's in it. A true sythetic oil is polyalkyleneglycol (chemical name). Mobil1 is Polyalphaolifins. So right there its not a full sythetic oil... Quote Link to comment Share on other sites More sharing options...
