Engine oil Shell or AMSOIL

Mobil 1 lacks the zinc for sure! Many people I know in Honda circles have done alot of oil research, as the flat rockers pads of the H22 VTEC engine get eaten away, especially with high lift cams. Most of us now run either Brad Penn, or Royal Purple HPS oil. I run the Rotella T6 in my Subaru and Acura, but the older Honda engine I still don't trust it.

Have used the T6 myself for years in assorted VW's and Volvos with reduced oil consumption as compared to the VW 504 oils.

It isnt either mentioned, but I have used the RotellaT6 with good results. I did this for my first oil change after I bought the car used. Not sure what the previous owner used, but the chains quieted down quite a bit.

Amsoil made the engine idle much smoother than any of the other oils have but every oil I've used but Mobil has been good as far as life and burn-off goes.

Shell Rotella T for the win - get it cheap at your local Walmart in gallon jugs. Side note on collapsed lifters - ATF Type F, added to the oil and a 5-10 min idle cycle before you change the oil can really help clean them out for cheap. Note, ATF has a lot of cleaners in it, and is thin, DO NOT rev it...just let it idle. Worked awesome on my old Coupe GT 5 cyl with horrid lifters.

Mine doesn't use any, and it gets an italian tuneup every time I start it. Running Rotella T6 5w40

I've been using amsoil for the past 2 oil changes. No complaints, car seems to idle a little better and cold start sooner.

I also started using it in my bike after switching from Mobile 1, and it's the best thing I've experienced so far with the wet clutch, keeping the shifting very smooth.

I just changed the oil in my car and I used Amsoil 5w40 European blend. No complaints so far.

I wouldn't use anything other than Amsoil I recently purchased some to change my R's oil soon.
