Another Mobil one user. Have 5 lexus's including an ISF and they all get the recommended weight Mobil One Full synthetic, and factory oem filters only. Have 400K on one and it doesn't burn a drop of oil and has had a hard life. I change every 3000Miles. I know its recommended to go longer, however the exhaust smells different and the car works just a smidge harder if if you extend the changes to recommended.

Haven't changed mine yet, but I always run Mobil 1 in my ES330. Change every 10k and it's still golden, no oil use at all at 285k miles.

Formerly Mobil1 5w-30. Now 5W30 Renewable Lubricants, Bio-SynXtra, Super High Performance. It tests out almost as good as Amsoil Signature Series, better than Mobil 1 of any flavor, and is best at controlling fuel dilution which is a huge problem for the OEM tune on our engines. Mobil 1 EP gave me the worst wear numbers I have ever seen from a synthetic. I only ran it once. Lots more in these threads:

Finally, 540RAT's blog has a massive amount of useful information. I don't agree with him on everything, but I do agree with his oil load rankings and I agree an oil capable of supporting a higher load will provide more reliable protection than one only capable of supporting a lesser load.

Got a good deal on penzoil platinum (not ultra platinum).

Debating if it's worth saving $30 and sticking with non ultra.

And is that last comment you? It's eerily similar to your above post. lol.

Mobil1. Sent off to Blackstone Labs every so often for analysis. They've verified that I could run 15,000+ intervals and still be fine, but I change it every 10,000.

I've ran Pennzoil Platinum with the OEM filter for 2 changes now, motor has been running smooth.

They really shouldn't be telling you that. They don't have the equipment to accurately measure fuel dilution, and it's the biggest issue we have. Tribologik, Test Oil, and others with ISO certification will be able to accurately assess fuel dilution. I've used Blackstone quite a lot, but I also know the limitations of what they can tell me accurately. Fuel and water dilution are not in any realm of accuracy for them.

I use Pennzoil Ultra Platinum when I can get the rebate. They're late on my last rebate so idk if I will go with them again. They need to pay up.lol
