Originally Posted By: CT8 What are the Detroit 2 cycles running in? I haven't seen one for years in any trucks . I used to see many when I drove truck in the 70 and early 80's. The turboed 92 series were really nice engines to drive, quiet and powerful. EPA forced Detroit Diesel to create a...

Excellent question, that I am not sure about. The only Amsoil specifically stating no VI's is the 10-30/30wt. Based on the robust tech specs, am thinking the VI's are not an issue, based on Viscosity cP ratings and HT/HS levels. My long term use of this oil and it's excellent oil pressure in...

Originally Posted By: Panzerman I have much experience with the old Detriot two stroke models. Use straight 40 wt. Do not use 15w40. You will not be able to keep it filled. When the four stroke series 60s came out ALOT of companies tried to just 15w40 for both. The two Stokes burned through it...

Appreciate the input. Every engine is different. I'm on our 3rd DD 2 stroke. Just put in 8G of Amsoil, so we'll see how it settles in to finally some good oil. One of my DD's (8V71NA), made it across country in 2 weeks of hard driving and used less than 2 qts in 7G capacity, with Amsoil...

I've heard of too many Michelin issues in the lower ranges. Including family members. Replaced a set of truck Michelins (265/70-17) with Yokohama AT/S in the same size. Customer loves them: better in all regards. They also grip like glue in the wet. Silica is the magic ingredient. Not the...

I have a 12 year old 1/2 Earthquake gun that still works great. It's held off top name brand tools in the shop. Only until this year did I step up and get a Cornwell 1250 lb/ft gun. It's far lighter and the extra torque helps at times. Just bought a Monster 1/2" 500lb gun, but it's got issues...

If I had to choose, definitely the Dart. Mainly based on the FIAT association. As a pro mechanic/tech, always dread working on domestics. My old Jeep isn't so bad, but the quality and engineering is laughable. Great lump of a mill, as the Brits say. I stick to German cars and own a few...

Hey Gang, Haven't been on in a awhile. Hoping to find some good data on this slightly obscure oil topic. As some know the old 2 cycle DD's "require" a straight 30 or 40 weight oil. The problem is finding good data with multi-weights that are comparable and meet DD CF-2 specs. I've found OE...

What is the root issue for wanting a low tech engine design? Oil related problems?

I've used a 1/2" HF Earthquake for 10 years. Professionally. Heavy, but very good.

Excellent advice. My account sells new snowmobiles with that oil as an option. And new Victory bikes during summer.
