I am in Jersey and it was 51 degrees maybe thats why, it wasnt that cold 2 days ago. Is it because the mobil 1 has a thinner cold weight of 0?

Hi WF ,
I already made a post regarding the poor viscosity of Mobile 1 5/30....it's a terrible oil. I highly suggest Motul X-cess 8100 5w 40. Not only has it improved cold starts but also has an amazing oil analysis and performance in all conditions. It also adhears to
8100 X-Cess
5W-40
Gasoline and Diesel Engine Oil
100% Synthetic
TYPE OF USE
8100 X-Cess is specially designed for the recent and powerful Diesel and Gasoline engines.
Numerous OEM approvals make this product multipurpose across all makes and models for maximum protection and a cleaner, more efficent engine.
Especially recommended for engines experiencing mild oil consumption.
PERFORMANCES
STANDARDS
ACEA A3 / B3 / B4
APPROVALS
API SL / CF
VW 502.00 505 00
BMW ‘Long Life’
PORSCHE CAYENNE 2002
Mercedes Benz 229.3
OPEL/GM Diesel LL B-025
The ACEA B4 performance requires an outstanding detergent / dispersent power and a better viscosity increase resistance due to soot produced by Direct Injection Diesel engines (except VW Unit Injector engines that require Motul Specific 505.01 5W-40)
The MB 229.3 standard is more stringent than 229.1 in terms of ageing resistance calling for extended drain intervals managed by the on board computer; detergent / dispersant power (see above ACEA B4) and fuel economy improvement of 1.2% versus a reference 15W-40.
The OPEL/GM Diesel LL B-025 standard requires two main properties of the lubricant : high HTHS and very low volatility to drastically decrease oil consumption.
Hope this helps.
