Rated 5 out of 5 by from been using this oil for several years now My 1986 Nissan Maxima has ~460,000 miles on it and I've been using 20/50 oil in it since I bought it in September of 1985. I've been using the Castrol GTX 20/50 High Mileage since it became available. Engine has original bottom end - had some head work done once when the timing belt broke - 460K miles - what more can I say

Rated 4 out of 5 by from best high viscosity motor oil the best motor oil of variable high viscosity (20-50) for aging engines on classic and antique motor cars. Not recommended for cold winter driving(<30F).

Rated 5 out of 5 by from Castrol Gtx High Milage 20w-50 Now naturally I thought that it was too thick but it made my engine nice and smooth with very little noise. I'd recommend putting in thicker engine oil on older vehicles with at most 100k+ mi. Castrol Gtx always meets my expectations every time. Never once used a different brand.
