[V8] Oil Weight

[Bill Hitzler]

I started using Mobil 1 0w/40 about 20 months ago and have run it year
round ever since. Summers get up to 70-75 degrees while winter will
occasionally dip to about -25. My 1990 V8 with 145,000 miles really
seems to like this oil and I do too. Don't worry if you've never run
synthetic in the vehicle before those concerns haven't been valid for at
least 20 years. Good Luck, William
