My 1990 Corvette ZR-1 with the Lotus designed LT5 will be going in for some servicing the first of next week, and I won't be able to get my usual Amsoil Z-Rod 10W-30 by then. The LT5 wants its high ZDDP levels, so standard oils in the 800-900 range won't work.
I was looking for the High Mileage Mobil 1 at the local Wal-Mart, and all they had was 0-20 and 5-30.
Being in Canada, some of the smaller brands that can be bought in the US aren't easily available up here.
Any plan B recommendations? Oils that would do lesser harm?
Liqui Moly MoS2 Anti-Friction 10W-40 has been recommended as a viable option, but I'm not that familiar with it. Seems the ZDDP levels are good in it.
