When I first got my 2005 s2000 I switch to Amsoil SS 10w-30. This was the SS before the recent reformulation (when XL was still only rated for 10000miles or 1 year)
Here is one random check on Blackstones. This was my first ever analysis of any oil, am new to the whole process. I understand I need to do it regularly to check trends. I lost no oil on the dip stick on the SS 10w-30.
Currently on my 2005 S2000 I have the new Boosted Amsoil XL 10w-30 in the engine. I have already gone 1 year on it and have sent a sample to Oil analyzer to see what it looks like. I did notice the dip stick lost about half of the oil. I do once a year oil changes because I come under 2500 miles and it's my once a week use/ HPDE car. I have already done the oil change and am on my 2nd year with Amsoil XL boosted. Awaiting results now from Oil analyzers.
Since I don't rack up enough miles and this car is used for HPDE I want to find an oil I can change once a year as being the only determinant. We don't get much HPDE where I am located, maybe 4 max a year.
Been reading and comparing prices of the new reformulated Amsoil vs Pennzoil.
I know people rave about Pennzoil Platinum Ultra. The Pennzoil Ultra 10w-30 is actually pretty cheap to buy online ($27 from walmart online). However limited info of specs online, I can't really compare it with say the Platinum or Amsoil. In another thread there seems to be indication that the Pennzoil Platinum is better in noack thank the Ultra. So I am confused if Ultra really is better at the current formulation. Could use advice on this.

I also have a Honda that takes 0w-20 and a VW that is currently on M1 Euro 0w-40. I'm thinking of switching all to Pennzoil. For the VW likely 0w-40.
(0w-40 euro ($28), 5w-40($43) )
