Well I asked for 6 quarts of Pennzoil platinum 5w-30, they came back with a box of six quarts, didn't notice until after changing the oil that it was Euro L not regular pennzoil platinum. Car is an old 1994 honda prelude with a dual cam non vtec 2.3 4 cylinder with 220,000 miles. Wondering if I should rush to change it or will it be okay for a few thousand miles. I normally wouldn't be worried but it says "designed specifically for diesel engines" on it and I read that it has a different additive package than most oils.
