I have used Amsoil exclusively since 1977 in everything I have owned.
I have never once had a oil leak, had to open up an engine for a single thing, nor any axle or trans problems.
btw-Always owned GM cars and trucks, is there another make?
btw
My last truck was a 1996 Chev Silverado Z71 Ext cab 4x4 with all the options. When new I changed it over completely to Amsoil, Engine-trans-axle and filters. I sold they truck with 50,000 miles (yearly oil changes) to a close friend in 2000. He wanted the truck to use in his business, service station and auto repair. He now has about 100,000 miles on it towing cars, plowing a lot of snow and traveling across the US. So far, the only thing to give him problems with the truck have been a faulty EGR at 80,000 and just recently the A/C switch. The engine, trans and drive line have never had a problem. His last 2 trans had trans problems from all the towing and snow plowing. His truck operates non-stop on most winter days. His last 2 trucks were worn out and done for at 100,000 miles, this one looks new and runs like new.
Right now I have Amsoil in these vehicle
1992 Chev Silverado 4X4
Purchased used in 2003 with 72,000 mile for plowing snow and a off-road truck (fishing, hunting, ATV'ing etc), changed to Amsoil 5W-30 right away and no oil consumption in 3,000 miles)
1993 Lumina 3.1 sedan
A family grocery getter, change oil once per year (about 3000-5000 miles), now has 61,000 miles
2001 GMC SLT Ext Cab Z71
New Nov 2000, installed 0W-30 in as soon as I got the truck home. Change oil once per year irregardless of the miles, now 37,000.
2002 Firebird Trans Am WS6 (Ram Air LS1 325 hp)
New Oct 2001 (car was built 9-11), changed to Amsoil 10W-30 after 1000 miles. Only waited that long because car supposedly had Mobil 1 from factory. Change oil once yearly, every Oct before parked for winter.
I know some are going to say 'sounds like a sales pitch". Well be that as it may, I refuse you use anything else even if you gave it to me. I have refused free oil changes with a new car. If you want to buy my 2001 GMC at 100,000 miles I can tell you from experience, the engine and driveline will be in the same condition there were when it was new.
