Need help on selection of motor oil

DIGItonium

What I would like to know is with winter approaching are you guys still running synthetic? I haven't switched to synthetic on my Z yet.

My dealer tells me that all 2010 370's come with the Ester oil and that dealers are instructed to strongly suggest synthetic only. I bought the 6 oil change maint plan (it saves me about $30 in 3 years). The plan docs say that it covers only the normal petroleum-based oil. I called the dealer and got the general manager. Even though the plan says it won't pay for the Ester oil except for the GT-R and the Altima Hybrid, the GM said that the plan also includes Ester oil for the Z. The dealer won't do an oil change with anything other than ester or another synthetic you bring in yourself on a 370.

I have been using Mobil 1 since it came out. I swear by it. There was an article somewhere that said Mobil looked at Ester oil and determined it was a high quality synthetic not unlike theirs.

My problem with the Nissan ester oil as a do it yourself oil changer was that it cost over $14 per quart at the dealer when I paid the stinkin' 8.75% tax. I get Redline 5W-30 for just under $10 per qt. delivered right to my front door when purchased by the case. No comparison, especially when exactly what the Ester oil is (and isn't) is still being debated.

Valvoline Full Synthetic. Easily the best choice, in my opinion. Mobil 1 is overpriced and not any better.
