Hi all,
My car low mileage daily now. 3k km since Feb. Town driving mostly due to change of workplace, previously 80km daily. Now thought of reverting to cheap mineral i.e Helix 15w40/ GTX 15w40. Sufficient protection? Car's total mileage around 230k, Campro engine. Change say every 6-8 months ok? |

QUOTE(zeng @ Jul 7 2020, 09:33 AM) Any 15W40 would offer even stronger (or thicker) oil film thickness protection than any 0W/5W-40 or 0W/5W30 with quite similar additive package . My old school mech has been using HX5 15w40 for the longest time I serviced with him before he retired. Always added one tin Bardahl B1 and he mentioned can stretch more than 5k kms. Guess there is some truth in his words. Next round change I would post some blotter test here.Yes, you get higher level of protection relatively . I would prefer one with a stronger European specs ACEA A3/B3 found in Helix 15W40 , not sure about GTX though . 6-8 months oil change ? From blotter spot tests performance , I personaly see no problem with up to 12 months or 8000-9000 km in a typical mineral engine oil . You can test and observe with blotters and evaluate , free of charge and convenient .  |
