Enginediy's autumn sale is running sitewide with 10% off everything, and it is the main offer on the page right now. This is the deal to use for most shopping, though a few specific items have bigger discounts if you are after one of those particular products.
On most purchases the 10% off sitewide autumn sale is your best choice. It applies to all engine models, motoring items and miscellaneous products on the Enginediy website, so you will see the discount automatically at checkout.
If you are buying the Turbofan Engine Model Kit check whether the 30% off sale on that specific item gives you a better saving than the 10% sitewide. On a $100 Turbofan kit, for example, 30% off brings the price to $70, a saving of $30, whereas 10% off would leave you at $90 and save only $10. The Turbofan sale cannot be combined with any other offer, so you have to choose one or the other.
If you are buying the Retrol Antique 4-stroke the same logic applies. The 20% off sale on that item alone beats the 10% sitewide sale, so use the 20% discount. Again, this offer cannot be combined with others.
If you are buying any two items and neither is the Turbofan or Retrol, the Buy Any 2 Get 15% Off sale will beat the 10% sitewide on most baskets. On two items totalling $120, for example, 15% off gives you a saving of $18, bringing the total to $102, whereas 10% off would save you only $12 and leave the total at $108. The 15% offer also cannot be combined with other deals.
If you are buying two or more items and one of them is either the Turbofan or Retrol calculate which single item's targeted discount saves the most, then compare that against the 15% off for the whole basket. If the Turbofan is 30% of a $200 order and the rest is $140, then 30% off the $100 Turbofan saves $30, whereas 15% off the entire $200 order saves $30 as well, a tie. Work out the exact figures for your own basket to see which comes out lower.
If you are a newsletter subscriber or signing up for the first time the newsletter signup may eventually bring special offers your way, but it does not carry an immediate discount you can use at checkout today.
The Autumn Sale Up to 30% Off Selected Products also runs until 31 October 2026, but this offer covers only selected items, not the full range. Check the Enginediy website to see which products qualify and compare the discount with the sitewide 10% before adding them to your cart.
The biggest percentage sale Enginediy has run in the 12 months to October 2026 was up to 50% off in July, so the current 10% sitewide and up to 30% on selected items are smaller than what the brand has offered in the past. Our team tested 10 Enginediy offers at checkout in that same 12 month window.
When you have decided which offer applies to your basket, compare the final totals and go with whichever one brings the price down the most. The sitewide 10% will apply automatically, but the item specific discounts on the Turbofan, Retrol and Buy Any 2 offers are sales that should show their reduced prices on the product page itself, so you will see the saving before you reach checkout.
