Auto-RX application change

When did RX change directions from 2oz per qt, then now to add the full bottle. I remember adding 9oz for a 4.5 qt engine before. Now I read pour a bottle in.

What are your thoughts on this? What if one engine takes 3.5 qts and another takes 6qts? That would be almost double for the small sump, or 1/2 strength for the big sump......

Must be new... Only know the "old" directions that were dependent upon sump size.

The stuff won't hurt the engine because it isn't a solvent, so maybe that is why it is ok and they have tested it?

I always dumped a bottle in anyways because it is pretty hard to measure a thick fluid from a black bottle that is oddly shaped IMO.

3oz per quart/litre or just a full bottle as I do. 2oz not enough imo.

IIRC Frank changed the instructions last year for simplification only- apparently, some folks had trouble figuring out how many ounces their vehicle required. The two oz./quart or 1:16 ratio is still valid, I believe they call out such for the real big toys such as semis...

And I thought I was bad with math..........Wow.

LOL - Yeah, counting by twos is a bear.

2 oz per qrt sounds pretty good. In my truck that would be a full bottle. The Jetta on the other hand still got a full bottle eventhough it only holds 4.5 qrts.

Yes I'm cheap so I want to buy less product. Why waste it?

There's always going to be a competition between ease of use (just add a bottle and go about your business) and "needs". It's all part of marketing. The distinctions are mainly where you have substantially different sump sizes. There's going to be margins that you want to cover in terms of potency.

For example: How many sales would be increased if the mileage was extended to allow seamless usage by the 3k/3m OCI types? How many do you lose below that due to complicated consumer adherence to counting miles ...or thinking that they're spending too much money on quick oil changes in too short a span of time?

So, you run it longer since there's no down side to it and increase your potential market.

In an ideal market for this product, you would have it limited to some "professional formula" type niche where only professionals used it.

I'm running my two bottles of RX in the BMW 7 quart sump for 6,200 miles (10,000 kms). Am I getting my moneys worth?
