Toyota requires oil changes every 5000 miles or 6 months to maintain the warranty. Bad advice..... -- Scott in Florida

You might want to consider trying Pennzoil Platinum or Quaker State Q Advance instead. Both oils have been beating Mobil 1 and Mobil 1 Extended Performance in engine wear tests, lately. For a little more technical stuff, the Mobil 1 5w-30 has a slightly higher viscosity of 11.3 centiStokes at engine operating temperature of 100 C / 212 F. The Pennzoil Platinum 5w-30 has a lower viscocity of 10.5 at that temperature. Sure, the 1 centiStoke (cS) difference is virtually nothing, when you consider that a 10w-30 /synthetic/ oil might have a viscocity of roughly 75 at cold startup during spring or early-fall (75 degree F) compared to a conventional oil's 100 at that same cold startup, a big difference in viscocity of 25 cS. (Much, much greater difference during winter temps., though.) The real reason I suggest the Pennzoil and Quaker State synthetics over Mobil 1 is their better showing lately in used oil analysis tests. Less iron, lead bearing, chromium, aluminum, and other engine wear metals are showing up in tests of the used oil. They're also showing higher TBN figures (the additives in your oil that help keep it healthy). Plus you can get the Quaker State for free right now at O'Reilly, after mail-in rebate. Free oil that is better than Mobil 1. Hard to beat that. Mobil 1 just has a huge advertising machine, but they're not better than the other two mentioned above.

(Mobil 1 has a huge advertising budget it has to pay for.)

(Mobil 1 has > a huge advertising budget it has to pay for.) On a per quart basis, the advertising cost is lower for Mobil 1. The reason why Pennzoil Platinum and Quaker State "may" be cheaper for now is that they are trying to "buy" market share from Mobil 1, who has long dominated the synthetic oil market (which they virtually created). BTW, Pennzoil-Quaker State Company is owned by Royal Dutch/Shell Group. Mobil 1 is a brand name of ExxonMobil.

Being that this car has only 2500 miles on it I was told by my Toyota dealer to wait until I have 20,000 miles before switching over to synthetic oil,and how does effect my warranty as far as oil changes,every 6 months?My dealer only carry's Mobil 1.
