Hi, guys. Whether I do not know it is possible to mention here at a forum trade marks, but consultation - for Bonny 92-99 engine oil Quaker State it well is necessary to me? (10w30 or 5w30 for Russian winter). And whether it is possible to use not mineral oil, and semisintetic ?

Quaker State in either 5w30 or 10w30 should be fine for a Moscow winter, not in Oymyakon, Moscow.

A semi-synthetic would also be OK. A straight mineral oil would not be suitable.

Thanks for the answer. In Moscow in the last winter some days were a - 32 C (in Siberia more warmly , usually in Moscow - 10 - 15 C). And Bonny it was heavy with oil 10w30.

Yes, last year was very cold in Moscow, it must be due to Global Warming.

At -32 C a bigger problem is your battery. At that temperature it may have only 1/3 of its usual power output.

The best option, if you can get it, would be a full synthetic. I don't know if that is an option for you.

I do not like semi-synthetics. It does not make sense to me to mix conventional and synthetic oils. Like mixing water and vodka, the result is less useful than the original ingredients are by themselves. :P

If the weather forecasters are predicting this winter to be as bad in Moscow as last winter, you should probably be shopping for an engine heater and battery heater if you must park in the cold.

Keep warm.

All will be good

I'd think about a dipstick oil heater for that car regardless of the oil used. Same for the battery, one of those heaters that goes underneath it.
