googlebot – How to enable instant scanning on the Google website?

We have an automotive website where we have different models of cars and bikes. We have product pages for each car / bike. Each page contains prices for products, offers, reviews, news, images and videos.

There are few problems we face:
1) If a new offer is launched, Google analyzes our website too late, so we can not display the offers in the title or description of Google results.

2) Similarly, if the product is reduced, Google has indicated as title and description, while once the user has accessed our website, it will appear as an abandoned product .

It's the same if we add a new image, news or reviews.

How can we instantly ask Google to retest if our product page is updated? We have thousands of product pages so that any manual is not scalable
