Quick verdict
Shopping for an ATV, UTV, or side-by-side accessory starts with a practical fork: do you need engine oil or wheel spacers? Maxima SXS 5W-40 Full Synthetic UTV Side-by-Side Engine Oil is the direct match for an engine-fluid purchase. SUPERATV 1.5-inch Wheel Spacers WSP18 ATV UTV Side-by-Side Polaris 4/156 is the direct match for a wheel-spacer purchase. They serve separate jobs, so the right choice follows the task rather than a performance ranking.
The listed prices are USD 164.99 for Maxima and USD 109.99 for SUPERATV, a USD 55.00 spread. Choose Maxima for the oil-focused description and New condition; choose SUPERATV for the wheel-spacer title and its New other (see details) condition.

Where each product wins
Maxima wins for engine-fluid needs
The Maxima description is specific to SXS engines and identifies a full synthetic, ester-fortified 4-stroke formula. It also describes oxidative stability at any temperature, shear stability, viscosity and film-thickness retention, and surface-active chemistry for keeping engine surfaces clean. For a shopper whose immediate need is engine oil, that specificity gives Maxima the more relevant role in this comparison.
SUPERATV wins for wheel-spacer needs
SUPERATV is the relevant choice when the shopping task calls for wheel spacers. Its title identifies a 1.5-inch size, WSP18, and Polaris 4/156. That makes the decision straightforward for someone comparing the listed wheel-hardware option with an engine fluid: the SUPERATV choice is about the wheel-spacer requirement, not oil.
Product notes
Maxima SXS Engine Oil
Maxima SXS 5W-40 Full Synthetic UTV Side-by-Side Engine Oil is the natural pick when a side-by-side engine-oil purchase is the goal. Beyond the full synthetic, ester-fortified formula, the description calls out a 4-stroke design, shear-stable performance that maintains oil viscosity and film thickness, and surface-active chemistry that attaches to engine surfaces and keeps them clean. Those details make it relevant for shoppers comparing engine fluids. The limitation is scope: engine oil does not address a wheel-spacer need. The brand is Maxima, the condition is New, and the manufacturer part number is 30-46901.
SUPERATV Wheel Spacers
SUPERATV 1.5-inch Wheel Spacers WSP18 is the focused choice when the shopping task is wheel hardware rather than engine oil. The title puts the wheel-spacer size, WSP18, and Polaris 4/156 in one concise product name. A limitation is the condition wording: New other (see details), which differs from Maxima's New label. Country of Origin is listed as United States, and Manufacturer Warranty is shown as Unspecified Length. The brand is SUPERATV. Its role remains specific to the wheel-spacer need, so it does not substitute for Maxima engine oil when the task is servicing a SXS engine.
Final choice by use case
- For SXS engine oil: Choose Maxima, whose title and description center on full synthetic 5W-40 oil for SXS engines.
- For wheel spacers: Choose SUPERATV, whose title centers on 1.5-inch wheel spacers, WSP18, and Polaris 4/156.
- If both needs are present: Treat them as separate purchases by purpose. Maxima covers the engine-oil job, while SUPERATV covers the wheel-spacer job.
The simplest decision is also the most reliable one here: select the product whose named function matches the work you need to address.
